HR 875 potentially protects millions of vehicles and engines that Circle 8 for more information 8 March 2013 | EngineBuilder THIS ISSUE: PG 12 >> Shop Solutions PG 14 >> Profitable Performance PG 17 >> Bearings Industry News can be harmed from E15. The bill states that the EPA was premature in permitting the sale since it is still unclear how E15 impacts tailpipe and evaporative emissions, OBD systems, materials compatibility and fuel efficiency. The analysis would consider a variety of issues including tailpipe and evaporative emissions, impact on OBD systems, materials compatibility and fuel efficiency. The National Academies would have 18 months to conduct an analysis, during which time sales of E15 blended gas would be halted. HR 875 has been assigned to the House Committee on Science, Space, and Technology for consideration. The Committee passed a similar bill last year but no further action took place. The U.S. Senate is currently considering another SEMA-supported bill (S.344) to ban sales of E15. HR 875 acknowledges that E15 causes corrosion with incompatible parts. Ethanol increases water formation which can then create formic acid and corrode metals, plastics and rubber. The EPA allows use of E15 in 2001 and newer vehicles, but agreed to make it “illegal to fuel pre-2001 vehicles” with E15. Supporters of the bill say that a required warning label on the gasoline pump will not protect consumers from accidentally misfueling these vehicles/engines.

The problem with this procedure is that it can be time consuming, costly and even dangerous. It is time consuming if each spring is compressed in a valve spring pressure tester and costly due to the fact that compressing many valve springs through several cycles accelerates wear and reduces the life span of the spring tester. Compressing springs in a vise or arbor press can be dangerous if the compressed spring escapes, thus becoming a projectile careening throughout the shop. We have solved these problems by making a fixture which holds four valve springs and is compressed in our 20 ton shop press. The fixture is made of two 3˝ x 6˝ aluminum plates with spring seats machined into them. Each of the four spring seats has a .375˝ diameter steel rod through the center to retain the spring if one should become dislodged during the procedure. Each steel rod is attached to the bottom plate and has enough clearance to move through the top plate. A recess is also machined into the top plate to accommodate the shaft on the shop press.

Kansas City, MO Manufacturer Shop Solution: Which Piston Rings to Use 7.3L Ford V8 Diesels? Your customer has a 1994 Ford 7.3L turbocharged diesel powered truck and needs piston rings. No problem? Not so fast! It will take asking more questions and perhaps examining and measuring some components to identify the correct rings. Between 1988 and 2003 Ford produced three versions of diesel V8 engines, all with the same engine displacement of 7.3 Liters. All of these engines had the same 4.110˝ cylinder bore. In 1994 all three engines were available. Each of these engines used a unique ring pack. The engines, their identifying characteristics and the rings for each are listed below. The 1988-94 naturally aspirated engines were great candidates for turbocharging. Companies such as ATS, Banks and Hypermax have sold a large quantity of turbo kits to enhance the performance of these engines. However, this can add to the confusion Connecting Rod Bore Standards To help me quickly set up my rod machine bore gauge for common connecting rod reconditioning I machine up some “standards” from good old rod cores.

But when it is all said and done, you’d wish you had built an engine that was engineered for your kind of driving, with a better look and you know you should not put one manufacturer’s engine under the hood of another’s car. It is just not right if you ask me. Here’s what you say, “You’ve been dreaming of this ride for 30 years since you sold the original one you had in high school – the car you raced outside of town along the tracks, you piled your buddies in the trunk to save a few cents at the drivein, you used to park in up at the dam with that bombshell that ‘got away’ (something about the ‘submarine races’) – you put the effort into find- 14 March 2013 | EngineBuilder THIS ISSUE: PG 17 >> Bearing Clearances PG 26 >> Today’s EFI PG 33 >> Chrysler Engines Performance ing the same year, make and model. But then you cut corners and buy someone else’s engine from some mail order place that will never have that same hot rod sound from under the hood. It won’t have the wheeze of a Flathead or the clatter of solid lifters. And it will forever look like 1968.” Like I said, this is your mantra, your sales pitch to someone who might just walk out the door and drive down to the local dealer and buy the latest ZZwhatever. Frank Freakin’ Bore-man! I remember when a guy had a engine, than started looking for a car to build around it. Now, you buy a frame and it is all welded-up and pretty. Ready to go with its Chevy motor mounts and a crossmember for a Turbo 350 transmission. This is often why good cars, not great cars, but good cars are often mistaken as “Kit Cars.” Pay your money and pick the color. That’s all you get. For hot rods, ’50s and ’60s street rods and muscle cars there is so much opportunity – more than ever before – to build a period-correct engine. And what’s going on in racing? Now they want to tell us that the same crate motor, with a slightly different camshaft, is a race motor. Powdered metal rods, hypereutectic pistons and all. Plug in and go racing. We’ll seal the motor with these special bolts that only our sanctioning body (and a handful of guys on the Internet) will have. We will equalize the playing field. Just make them all the same. Now racing is affordable for the masses. Except when you break. Than you must take the crate motor to a licensed and bonded shop that we have chosen to allow to take your money. Plus, to insure there is no cheating, we need to make sure the same aftermarket parts go back in these motors and we need you to pay extra so they can be distributed through a dealership and have the O.E.M. part number on the box. Oh, don’t worry that many have the idea that, “It’s not racing if you’re not cheating.” And that the aforementioned sealed bolts can be bought online. Or that folks have gone as far as trying to disguise an aftermarket block and heads to look like the O.E. Or that someone with enough time can turn the motor on end and shake the stock hydraulic lifters out of it and with great patience replace them with racing hydraulics or even solids through the distributor hole. Let’s be honest. Once the bolts can be obtained, the sky-is-thelimit. And than there’s that argument that the Tech guy who works the track Saturday night doesn’t have the ability to check a variety of engines to make sure they are all complying to the rules. He’s now an expert on sealed bolts and unmodified crate motors? The truth is, rules only apply to the winner. If something seems to be unfair, there is always the tear-down. And this is true whether it’s a real race motor or a crate motor. Don’t get me wrong, I like the idea of making the sport a little more competitive and a little less expensive. But just like anything the government gets involved with, beware of unintentional consequences that arise. And when was it ever fun to go to the races and Circle 15 for more information EngineBuilderMag.com 15 Performance not have a favorite manufacturer’s brand to root for? You show up with an AMC V8 and you get my support. Give me the underdog every time. At bare minimum I want to see Fords, GMs and Mopars mixin’ it up. The importance of these ideas can’t be overlooked. Today’s grocery getter might last 11 years, get 300,000 miles on the clock and with good maintenance, the motor will never be touched. This is not an indicator of good things to come for our industry. From what I see, the vast majority of smaller shops’ engine builds are for restorations and race cars. Now they want to take that away from us as well. And make no mistake about it, the guys wearing the black hats in this drama have a lot larger checking accounts to market and promote their plain vanilla crates than we have to promote good old American diversity. This is an industry problem and the industry needs to address it. Many performance parts manufacturers are just as upset with the trend that is circulating around the country as the machinists who install their parts. Parts distributors are just as unhappy and from what I hear, many of the racers who have tried racing with the crate aren’t always that happy either. Especially when they find out the motor they were planning on running is illegal this year. That bites twice. I’m no expert, and I know less about race track promotion. But if ticket sales are any indicator, the fans may not appreciate crates under the hood either. Unfortunately the only places I see to put any pressure to fight back against this trend would be on the promoter, sanctioning body or tracks, and the racer. These are the pressure points because this is where the money is. Unlike a street motor where we can sell a certain amount of “sex appeal,” in racing we have to go for the dough. It might hurt for a while, but if no machine shop supports the crate engine programs, if the racer can’t find a place to fix his motor and if track owners and promoters get complaints from the racers and fans we can hope to stem the tide and return to a more traditional form of racing. One with variety, diversity and yes, a certain amount of stretching the rules. Smokey Yunick once said something like this when asked about a potential rule violation. He stated, “Because it didn’t say I couldn’t.” And this to me ladies and gentleman defines racing. As usual, I’m not the bearer of good news, yet I know for the most part that I’m preaching to the choir. So see this as a friendly reminder that yours is not the only business affected by crate motors. This is an industry problem that will need to be addressed by all aspects of the industry. To turn our backs on it any longer will only mean acceptance and another piece of the pie taken from from everyone’s plate. If diversity is king, then “Long Live The King!” As for the crate? RIP. ■ Circle 14 for more information 16 March 2013 | EngineBuilder Circle 16 for more information Feature Bearing Clearances How Much Is Enough? TECHNICAL EDITOR Larry Carley firstname.lastname@example.org I s it better to build an engine with tighter bearing clearances and run it on low viscosity synthetic motor oil, or is it better to build an engine with more traditional or even looser bearing clearances and use heavier viscosity oil? The short answer is it depends on the engine, the application and the type of oil used. Tight bearing clearances and relatively thin synthetic multi-viscosity motor oils work well in many performance applications from NASCAR and circle track racing to drag racing. Keep in mind, however, that most of these engines are purpose-built engines that are machined with exacting tolerances. Crankshaft journals are precision ground to be as round, flat and true as possible, the journals are micropolished to a mirror-like finish of a couple microinches Ra or less, the bearings are precision fit to exact tolerances using a bore gauge and micrometer (not deformable plastic gauge), and the engines are run on high quality synthetic racing oil, not ordinary motor oil. The oil clearance is the gap between the inside diameter of an installed bear- ing and the outside diameter of the crankshaft or camshaft journal. The clearance is measured 90 degrees to the bearing parting line, which is the thickest part of the bearing (bearing thickness tapers slightly toward the parting line). Reducing the oil clearance between the rod and main bearings and the crankshaft has a number of advantages. A smaller gap spreads the load over a wider area of the bearing surface and distributes pressure more uniformly across the bearing. Thatâ€™s good, provided the bearing is strong enough to handle it. A smaller gap also decreases the volume of oil that has to flow into the bearing to maintain the oil film between the bearing and shaft. Thatâ€™s also good, provided the oil is thin enough (low viscosity) to flow well into the bearing. This also reduces the amount of oil pressure the engine needs, so some extra horsepower is gained by reducing the load on the oil pump. Reducing the oil clearance between the rod and main bearings and the crankshaft has a number of advantages.

Most of these engines are running rod and main bearing clearances of .001˝ or less, and they are doing it with low viscosity racing oils such as 0W5, 0W30 and 0W50. These racing oils are as thin as water and are highly friction modified. They also contain extra anti-wear additives such as ZDDP (phosphorus levels up to 1,850 ppm or higher) to protect the cam lobes and flat tappet lifters. These are race-only oils and are not recommended for street use because they do not contain the same detergents, dispersants and corrosion inverters. hibitors as ordinary motor oils.

But what works great for NASCAR may not work in other Circle 18 for more information 18 March 2013 | EngineBuilder Circle 19 on Reader Service Card for more information forms or racing or on the street. One of the disadvantages of closer bearing clearances is that it can increase both bearing and oil temperatures. That’s no problem as long as the bearings and oil can handle the heat, but if they can’t it increases the risk of lubrication breakdown and bearing failure. That’s why high quality synthetic motor oil is absolutely essential if you are building an engine with tighter than normal clearances. The old rule of thumb is to provide .0007˝ to .001˝ of bearing clearance for every inch of shaft diameter in a stock engine. Consequently, if the crankshaft has two-inch diameter journals, the rod and main bearings should be assembled with about .0015˝ to .002˝ of clearance. For performance applications, some bearing manufacturers recommend adding an extra half a thousandth of clearance. Why? Because the rod bores don’t stay round in a performance engine at high rpm. When the piston reaches top dead center on the exhaust stroke, inertia stretches the rod and elongates the bore on the big end of the rod. This, in turn, deforms the bearings and reduces bearing clearances on the lower rod bearing while increasing it on the upper rod bearing. For high revving performance engines, some bearing manufacturers recommend rod bearing clearances of .002˝ to .003˝, with an absolute minimum clearance of no less than .0015˝. The tighter the clearances, the tighter the geometry requirements are for the crank journals (as round, straight and smooth as possible with little or no taper). Street engines can benefit from tighter tolerances and thinner oils for everyday driving. But when power adders such as nitrous oxide, turbocharging or supercharging are used, or the engine’s power output gets up in the 450 to 500 plus horsepower range, looser bearing clearances are probably safer to accommodate crankshaft flexing, main bore and rod bore distortion. The same reasoning applies to drag motors, truck pull engines and other performance engines that produce serious horsepower. Many of these engines are built with rod and main Circle 20 for more information 20 March 2013 | EngineBuilder bearing clearances in the .0025˝ to .003˝ range. For the Saturday night dirt track racer, clearance is your friend because of the contaminants that often get into the crankcase. Looser is usually safer. Rod and main bores should be as round as possible with no more than plus or minus .0005˝ of variation for a performance engine (.001˝ is close enough for stock). You also have to take into account the fact that the bearings themselves may not be perfect. Manufacturing tolerances of up to plus or minus .00025˝ are not unusual in some bearings, while others may vary only .00015˝ or less. Main bore alignment is also critical. Some bearing manufacturers say adjacent main bores should have no more than .0005 inch of misalignment (.001˝ overall) if you are using tri-metal bearings, and no more than .002˝ of misalignment between adjacent bores (.002˝ overall) with aluminum bi-metal bearings. One of the advantages of looser bearing clearances is that it allows more room for “slop,” which is important if the crankshaft isn’t machined to near perfection or there is some misalignment in the main bores. Wider bearing clearances do require a heavier viscosity oil (such as a 20W50 multi-viscosity oil or a straight 30, 40 or 50 oil). The heavier viscosity oil is absolutely necessary with wider clearances to maintain the oil film between the bearing and shaft so the bearing isn’t starved for lubrication. This also requires more oil pressure from the oil pump and/or more oil volume. The amount of oil that is actually between the bearing and shaft surface at the point of highest load isn’t much. Though the installed gap between the bearing and shaft may be .001˝ to .0015˝ or more, the oil is displaced when the bearing is loaded. At its thinnest point, the oil film may only be .00002˝ thick (1/100th the diameter of a human hair!). That’s not much oil between the metal surfaces, but it doesn’t take much to maintain hydrostatic lubrication. When the shaft starts to turn, an oil wedge forms between the shaft and bearing that lifts the shaft up and away from the bearing surface. The shaft then glides on the oil with minimal fric- THIS ISSUE: PG 26 >> EFI Systems PG 33 >> Chrysler Engines PG 50 >> Stroker Guide Feature tion.

Polishing the crank can reduce surface roughness on the journal but it won’t get rid of the lobes or ribbing.

The top layer of Babquickly wiped away if the engine bitt acts as a dry film lubricant when starves for oil when it is running there is no oil between the shaft and under heavy load or at high rpm. bearing.

One of the reasons why many performance engine builders use tri- Circle 21 for more information EngineBuilderMag.com 21 Feature metal bearings is because they want bearings that have good seizure resistance in high rpm applications. Trimetal bearings also handle high engine loads well and have good fatigue resistance. The Babbitt surface layer also provides embedability if dirt or debris gets past the oil filter. Tri-metal bearings are typically recommended for use with forged steel crankshafts. Aluminum bi-metal bearings, by comparison, have high wear and corrosion resistance. With harder aluminum/silicon alloys, they can also handle higher loads while providing good antiseize properties. Aluminum bearings are often recommended for cast iron cranks because they have a polishing effect on the journal surface. Whatâ€™s more, according to some bearing manufacturers, a high silicon alloy aluminum bi-metal bearing will actually resist seizure longer than a tri-metal bearing if the protective oil film goes away. That brings us back to the oil and bearing clearances. The oil doesnâ€™t care what kind of bearing and shaft it is lubricating. It only needs to maintain enough oil film between the two surfaces to provide hydrodynamic lubrication and prevent Regardless of what type of bearings you put in an engine or how close you set the bearing clearances, always use plenty of assembly lube to coat the bearings. And use proper break-in oil when you run the engine for the first time for extra anti-wear protection. Circle 22 for more information 22 March 2013 | EngineBuilder THIS ISSUE: PG 26 >> EFI Systems PG 33 >> Chrysler Engines PG 50 >> Stroker Guide Feature metal-to-metal contact. There has to be enough oil pressure and flow to keep the bearings lubricated and cooled, and the oil itself has to have enough shear strength so it isn’t pushed out of the gap between the bearing and shaft at the point where the load is greatest. Multi-viscosity synthetic motor oils flow more easily than conventional straight weight oils at both low and high temperatures. So they can handle cold starts as well as elevated operating temperatures (which is really important with turbochargers). To reduce friction and improve fuel economy, most late model stock engines are factory-filled with 5W20 or even 0W20 oil. Combined with tighter engine assembly tolerances, these oil and bearing combinations work relatively well for everyday driving and even mild performance use. For racing applications, though, the oil needs to be formulated specifically for racing – especially if the engine has a flat tappet cam that requires plenty of ZDDP in the additive package. You can get oil viscosities ranging from 0W5 to 120W60, with 15W40 being a popular viscosity for stock car racing, road racing and spring cars. For wider bearing clearances, some prefer to use a heavier 15W50 or 20W50 oil. In drag racing Top Alcohol and Pro Mod classes, AHDRA Nitro Bikes and blown alcohol tractor pulling, 20W60 may be the lubricant of choice. For NHRA Top Fuel dragsters and Funny Cars, a 70WT oil might be used. So the type of oil that’s used will depend on the application and the bearing clearances inside the motor. An additional layer of protection can be achieved by installing coated bearings. Various types of proprietary coatings are available that provide scuff resistance where there is no oil between the bearing and shaft. Such coatings cost extra, but are good insurance against dry starts and may save a crank if the engine loses oil pressure in a race. Finally, regardless of what type of bearings you put in an engine or how close you set the bearing clearances, always use plenty of assembly lube to coat the bearings. Also, use the proper break-in oil when the engine is run for the first time. Break-in oils are typically a straight 30W oil without friction modifiers for fast ring seating. But they also contain extra ZDDP anti-wear additives to protect the cam and lifters. The break-in oil can then be drained and replaced with the type of oil (conventional or synthetic) that will be used from that point on. Be sure to tell your engine customer how important it is to use a high quality oil and that it has the correct viscosity to match the bearing clearances and lubrication requirements of the engine and application. ■ For more information and articles about engine bearings, visit our website and use the search feature.

EFI goes far beyond a replacement for a carburetor, and the electronic part of the equation is where these systems seem so complicated. Many EFI systems give you the ability to control a wide range of parameters of the vehicle, so it’s more involved than simply controlling fuel flow. It comes down to being able to completely control the engine and the vehicle’s systems by carefully calibrating fuel and timing at specific load levels.

EngineBuilderMag.com 27 Feature Matt Cramer of DIYAutoTune.com, says they sell the MegaSquirt line of engine management systems. These are available in everything from the old-school solder it yourself kits to polished plug and play systems. The latest addition to the company’s lineup is the MS3- Pro, a sealed control unit aimed at a somewhat higher end market than its previous version. Cramer says that these systems can be used with either throttle body injection or multi-port systems. The biggest changes Cramer says he has seen in the past few years is Circle 28 for more information that the OEM systems continue to grow in complexity, driven primarily by emissions and CAFE standards. But he says the aftermarket tends to catch up pretty quickly. “The biggest change I’ve seen in the aftermarket world is price,” says Cramer. “Our MS3-Pro sells for $1,199 with a wiring harness, and even a year ago you would’ve had to spend around three times that to get the sort of features it offers.” Our experts say that for old-school carburetor guys, there can be some perceived challenges at first dealing with the intricacies of an electronic fuel injection system but if you have a good understanding of how a carb and engine work, the transition will actually be seamless. “Like anything, learning a new skill takes time,” says Wright. “If a guy genuinely understands how an engine works and how to tune a performance carb then the transition to EFI is a lightbulb moment in their career and it’s really quite a joy to experience. On other hand, if your knowledge of carbs is limited to ‘look up what the manufacturer suggests and bolt it on,’ then the transition to EFI will be more turbulent.” Some experts suggest that the biggest obstacle a “carb guy” may face is the fear he’s installed in his own mind. “I break the EFI system into three parts,” says Andrew Starr of Hilborn (www.hilborninjection.com). “The fuel system requires the correct placement of the components, which is detailed in our supplied schematic. The electronics are supplied with a schematic while the wiring is easily modified to fit the vehicle and, yes, a solder gun is mandatory (no butt-connectors, please). And if you’re installing an individual runner (IR) intake manifold the technique of tuning the butterflies is presented in video form on our website. So any old school carburetor guy can do EFI once they get over their initial anxiety. Most people find tuning an EFI system easier than a carburetor when they’ve had a chance to work with it.” Erik Brock of MSD Performance (www.msdperformance.com) says instructional videos can help answer basic installation and setup questions. “We also make it a point to visit many Circle 26 for more information 28 March 2013 | EngineBuilder Circle 29 on Reader Service Card for more information Feature engine builders in order to answer questions and take feedback.” Eric Blakely of Edelbrock (www.edelbrock.com) says they have made it a priority to get their customers more comfortable with EFI by eliminating the computer from the equation and offering EFI systems with a simple-to-use handheld calibration module. “Our E-Street system has a simple to use E-Tuner. These handheld modules simplify the setup process by asking basic questions in order to get the right information for the system. They also make it convenient to tune right at the vehicle, instead of using a laptop computer and loading a modified tune,” Blakely says. “Our new EStreet EFI system will take this one step further by eliminating the cables and will communicate directly with the ECU wirelessly.” Aftermarket EFI systems are available in many formats from throttle body TBI to multiport, but it depends on what your customer needs to determine which system is best for your application, say our experts. Cramer says that DIYAutoTune’s control units can be used with both types of setups, although most of the fuel delivery hardware they sell is geared to multi-port. “Throttle body injection is cheap and straightforward to install and we’ve had thousands of customers go that route and they’re very happy. At the same time however, it will never perform to the level that a good MPFI setup will, which is exactly why OEMs quit using it. Multi-port injection tends to get better fuel distribution from the start, and sequential systems let you tune the fuel on each individual cylinder as well if you want to get it perfect. There’s a reason OEM throttle body injection seldom showed up in high performance applications.” When NASCAR switched to EFI at the start of the 2012 season, some said that it wouldn’t offer fuel savings because a carb atomizes the fuel better than EFI. Our experts pointed out that the carb may make more peak power but it is not as efficient throughout the whole rpm range. The carburetor, with its booster, is a much more efficient mixer of the air and fuel than the typical EFI system. According to Brock, in some cases, a carburetor may atomize fuel better than EFI. “Across a wide range, port fuel injection will have better cylinder-to-cylinder distribution and atomization at much less development cost,” he says. “The problem with carburetors is tuning fuel use efficiently throughout the operating range,” says Hilborn’s Starr. “NASCAR engines spend most of their time at WOT and are tuned accordingly.” Cramer says the biggest disadvantage of EFI is that all those features can give you enough rope to hang yourself if you don’t know what an engine needs and just start smacking buttons. The power to tune the engine perfectly also gives you the power to tune it imperfectly. Circle 30 for more information 30 March 2013 | EngineBuilder Circle 31 on Reader Service Card for more information Feature Still, Cramer says horsepower and torque are easy enough to see in a dyno pull. And with EFI engines, all else being equal, will generally make more power all across the rpm range on average, where carbs tend to be a little peakier. Holley’s Burnett says that while basically getting the same job done, the carburetor and EFI units do so a bit differently. “Some racing classes only allow carburetors to be used and will continue to do so for many years to come. Other types of car restoration professionals will continue to put what came on the car originally on their vehicles and that will sustain the carburetor in the same manner. Our EFI systems allow a customer to control many different functions all within one unit and to do so easily.” Tuning an EFI system REALLY does require the engine tuner know about engines, say our experts. “That’s a big challenge these days in the EFI world actually,” explains Haltech’s Wright “You have a bunch EFI systems such as this one from Holley come equipped with 4 programmable inputs and 4 programmable outputs and is billed as the replacement for a 950 carb. It fits most vehicles with up to a single power adder. of tech-savvy computer geeks tuning engines that they know very little about.” The best tuners have a foot in both camps, say our EFI experts. “No doubt, the guys who you’re looking for as a tuner know cars and com- puters,” Wright concludes. “As far as computer skills are concerned, if you can use Windows you can probably learn most EFI systems. The true professionals understand engines and they can operate a laptop.” ■ 32 March 2013 | EngineBuilder Circle 32 for more information Feature CONTRIBUTING EDITOR Doug Anderson email@example.com Photography by Nancy Swafford C hrysler made some major changes in their engine lineup starting in ’07. They replaced their four cylinder engines in everything but the PT Cruiser in ’07, updated the 4.7L V8 in ’08, added variable valve timing to the Hemi in ’09 and replaced their V6 motors with a new 3.6L DOHC beginning in ’10, so all of their engines were either new or improved by 2013. With that in mind, here’s an overview of all the changes they made along with some detailed information on a couple of them that we haven’t discussed before including the 4.0L SOHC V6 and the dual plug 4.7L. Let’s start with their four cylinder engines. Chrysler teamed up with Mitsubishi and Hyundai to design a whole new family of four cylinder engines that were used by all three companies, although each one modified the basic engine design to fit their needs. They created the Global Engine Manufacturing Alliance with five factories in the US, Japan and Korea that built about 2,000,000 en- gines a year. These were usually called the “GEMA” motors by people in the industry, but Chrysler named theirs the “World Engines” and installed them in most of their front wheel drive vehicles beginning in ’07. There were three different engines in this family including a 1.8L, a 2.0L and a 2.4L with an aluminum block along with an aluminum DOHC head that had “dual electrohydraulic VVT” on both the intake and exhaust cams. They all had a crank driven module inside the pan that incorporated the oil pump and two counter-rotating balance shafts, too. There weren’t very many of the 1.8L motors built because they were only available in the base model of the ’07-’09 Caliber that usually came with the optional 2.0L that was standard in the small 2WD Jeeps. The most popular “World Engine” was the 2.4L that was installed in all of their mid-sized cars along with the 4x4 Jeep Compass and Patriot. There were a few of the turbo 2.4L motors installed in the Caliber SRT4 in ’08-’09, but they were pretty rare. These “World Engines” were often criticized because they were a bit rough and noisy and they didn’t make much power at the low end, but they were cheaper to build than the original 2.0L/2.4L motors and they got better fuel economy, so Chrysler was happy with them for awhile. The chart on page 36 includes the applications, dates and VIN codes we found for each engine. This is our best take on these engines based on the information we found in a variety of sources that didn’t always agree, so consider it an overview and proceed with caution. We have included it to make sure you know about the “World Engines” that replaced the Chryslerbuilt 2.0L and 2.4L motors in everything but the PT Cruiser beginning in ’07 (Chrysler continued to use their old 2.4L motor in the PT 34 March 2013 | EngineBuilder Circle 35 for more information Feature Updating the CHRYSLER ENGINES This next generation of their World Gas Engines – called the “Tigershark” family – will be installed in the new Dodge Dart in 2013, but the 2.4L engine is scheduled for “late introduction” so we haven’t seen any of them yet. All the rest of their front wheel drive cars and the mini-sport utilities will continue to use the existing 2.0L and 2.4L “World Engines” through 2013.

It replaced all six of their existing V6 engines including the 2.7L, 3.3L, 3.5L, 3.7L, 3.8L and the 4.0L in all of their cars and trucks by the end of 2012. We knew that all of these existing engines were “lame ducks,” but we didn’t know exactly when they were replaced or what might have been changed since our last update in ’07, so we spent a lot of time in the Hollander manual, Mitchell Online and the Chrysler parts book to come up with some answers. With that in mind, let’s take a look at them, one at a time, starting with the 2.7L V6: •The 2.7L/167 CID DOHC engine was used up through 2010. The VIN was changed from ‘R’ or ‘T’ to ‘D’ in ’09 and ’10, but the engine was pretty Chrysler used a link chain (front) instead of a roller chain to drive the intake cams beginning in '09 or '10. Chrysler teamed up with Mitsubishi and Hyundai to design a whole new family of four cylinder engines that were used by all three companies. These were usually called the “GEMA” motors by people in the industry, but Chrysler named theirs the “World Engines” and installed them in most of their front wheel drive vehicles beginning in ’07. through ’10). Rebuilding the GEMA motors at a reasonable cost may be a challenge because the parts, including the balance shaft/oil pump module that has to be replaced because it can’t be rebuilt (you can’t even take it apart), are pretty expensive. Chrysler and Hyundai have better access to parts and cores than we do and they’re both selling their rebuilt GEMA engines for around $3,000, so that’s probably a pretty good benchmark to keep in mind. I personally know of one rental car company that spent nearly $5,000 apiece to install five of the remanufactured 2.4L engines in some 2011 Hyundai Sonatas that ended up with the wrong oil filters. That makes me wonder how many customers will be in the market for one of these engines when the time comes. But that’s not the end of the story for the four cylinder motors. Chrysler bought out their partners in the Global Alliance in September of ’09 and announced that they were going to replace their GEMA engines with a new family of four cylinders that would be better than the existing engines and incorporate the latest technology from Fiat. 36 March 2013 | EngineBuilder They’re replacing the 1.8L with either a 1.4L or a 1.8L from Fiat, but they’ve updated their 2.0L and 2.4L with a die-cast aluminum block that has a cast iron bedplate along with a new head that has roller cam followers and comes with a sophisticated intake manifold. Both of these Chrysler engines will have four valves per cylinder, but the 2.4L will be a SOHC motor that incorporates the Fiat “MultiAir variable-valve timing technology” for the first time in a Chrysler-built engine. BROUGHT TO YOU BY: ENGINE & PERFORMANCE WAREHOUSE much the same. •The block that was modified for starter clearance in ’01 was used up through ’10 along with the new “lightweight” head castings that came out in ’06. You can identify the lightweight heads visually or by the 4892064AA/4892068AA casting numbers. There’s only one difference in the engine after ’07: Chrysler changed the width of the primary chain and used two link chains instead of the roller chains to drive the intake cams beginning in ’09 or ’10, but we don’t know exactly when they made the change because they’ve superseded all of the original timing sets to the later design that requires new gears and chains along with all four cams and a different water pump. The bad news is that none of these late model timing components are available in the aftermarket, so you better make friends with your Chrysler dealer if you decide to rebuild one of these engines with all the latest parts. •The 3.3L/201 CID OHV engine was used in the minivans up through ’10 before it was discontinued. The VIN code was changed to an ‘E’ in ’09 and ’10. This engine got new heads in ’01 and a new block casting (4666031AB) in ’07, but nothing was changed after that so the engine stayed the same up through ’10. •The 3.5L/215 CID SOHC engine was used in both the front and rear wheel drive cars up through ’10. The VIN codes can be a little confusing in ’09-’10 because the FWD cars were a VIN ‘V’, just like the RWD cars, even though the engines weren’t interchangeable. The long block remained the same as an assembly, but the short block had new, heavy duty, forged steel rods that had a cracked cap and a tapered small end that used a unique pin bushing. The piston was changed to a lightweight design that helped offset the additional weight of the new rod, so the combined weight of the early and late piston/rod assemblies is nearly the same. Knowing that allowed us to use the early rods and pistons in the later engines until DNJ began supplying the late, lightweight piston. The bad news is that there aren’t any pin bushings available for either rod, so we’re having them made for both applications. •The 3.7L/226 CID SOHC motor was used up through ’11 in the Dodge Dakota and the Nitro and up through ’12 in the Jeep Liberty and the Dodge pickups. It was always identified as a VIN ‘K’ from ’02 thru ’12. The 3.7L used the same short block from ‘02 through ’12 except for the change to the NGC tone ring in ’04. The heads got new kidney–shaped chambers in ’05 and EGR was added to the left head in ’07, so there’s a 53020984AC head casting on the right side and a 530200983AD casting WITH EGR on the left side.

Watch out for the VIN codes when selling one of these engines, because they vary from year to year and both the front and rear wheel drive applications share the same VIN code in ’10. The Wrangler was always a VIN ‘1’, but the minivan was an ‘L’ in ’07, a ‘P’ in ’08-’09 and a ‘1’ in 2010. •The 3.8L was usually updated when the 3.3L was revised because they’re both part of the same family, so the 3.8L got the new heads in ’01 and the 4666031AB block casting with the extra bolt holes for the RWD Wrangler in ’07. Nothing was changed after that, so the same long block was used for everything up through ’11, although the complete engine assemblies came with different pans and front covers, depending on the application. •The 4.0L/241 CID SOHC is the last V6 motor on our list. It’s a stroked version of the 3.5L so they share a lot of common parts, but there are some important differences, too. The 4.0L showed up in the Pacifica Limited and Touring editions along with the Dodge Nitro R/T in ’07 and it was used in the Chrysler Limited minivans from ’08 through ’10. The new 3.6L Pentastar engine replaced the 4.0L in everything except a few of the Dodge Nitros in 2011. Be careful when cataloging these engines, because the VIN codes overlap again. The FWD applications were always a VIN ‘X’, but the RWD Nitro that was a VIN ‘6’ in ’07 and ’08 became a VIN ‘X’ from ’09 through ’11. That can create a problem if you sell an engine based on the VIN code without knowing the application, because they have different front covers so they’re not interchangeable. •It took us a while to figure out how to catalog the 4.0L engines because Chrysler says there are four different short blocks including early EngineBuilderMag.com 37 Feature Updating the CHRYSLER ENGINES special bushing in it. Oversize OD rod bearings are available, but no one offers the special pin bushings so we’re having them custom made for this application. and late versions of both the front Connecting Rods and rear wheel drive motors, but The 4.0L uses the exact same rod that there’s actually only one short block showed up in the 3.5L beginning in along with two long blocks.

Pistons The piston for the 4.0L looks a lot like the one that was used with the new rod in the 3.5L beginning in ’07, but Rebuilding The 4.0L: Blocks There are two block castings, a 4593586AA and a 4593586AB, but they’re both the same and they’re identical to the late 3.5L except for the big mains. They’re easy to tell apart because there’s a small ‘3.5L’ or ‘4.0L’ on the block right below the casting number. Crankshaft The 4.0L motor has a forged steel crank that looks just like the one that’s used for the 3.5L, but the mains are bigger they’re 2.717” instead of 2.5202” - and the stroke is 10mm longer so it measures 3.58” instead of 3.189”. This crank is easy to identify because it has “4 0” forged on the counterweight right behind the third rod journal. The big main bearings for the 4.0L are available in the aftermarket now. The 4.0L has a forged steel rod with a cracked cap. The small end is tapered and has a bushing. The piston for the 4.0L (right) looks like the one for the late 3.5L (left), but the compression height is 5.0mm lower to compensate for the longer stroke. the compression height is 5.0mm shorter because the stroke is 10.0mm longer. Modifying the compression height of the piston allowed Chrysler to use the late rod from the 3.5L along with a common deck height so they could install the same heads and timing components on both engines. This piston is available from DNJ, too. Rings The 4.0L uses the same 1.2mm/1.5mm/2.50mm rings that were used for the late 3.5L beginning in ’07.

The right hand cam is a PN4593616AA and the left hand one is a PN4593618AA. Chrysler recommends replacing the bolts for the cam sprockets any time they’re removed. The front cover for the FWD 4.0L engines has a flat pad in the middle with three bolt holes for the torque axis motor mount. Timing Components All of the timing components used on the 4.0L Heads The 4792728AA or 4663894AC head castings that came on the 4.0L are the same ones that were used on the 3.5L beginning in ’04. Both of these heads have provisions for EGR so we always plug the holes to make sure that the customer doesn’t forget to plug the one that isn’t needed for his application. Everything else that’s up topside, including the cam followers and rocker assemblies, is the same except for the cams. Camshafts The cams for the 4.0L are unique to this application. Chrysler says “they have a higher lift/profile for The 4.0L block looks identical to the one for the late 3.5L except for the bigger mains, but it's easy to tell them apart because there's a '4.0L' cast right on the block under the casting number.

Front Covers The only difference between the front and rear wheel drive long blocks is the inner front cover. The one for the FWD cars is a 4892137AA/AB/AC that has a flat pad on the top with three bolt holes that are used for the torque axis motor mount. There are three different castings with AA/AB/AC suffixes and Chrysler still lists two different part numbers, but we’ve seen all three of them and couldn’t find any difference, no matter what Chrysler says. There are three different castings for the front cover that’s used for the RWD motors, too, with a 4892266 casting number that has AA/AB or AC suffixes.

Final Thoughts On The 4.0L The 4.0L is easy to catalog because there’s only one short block along with two long blocks that have different front covers, depending on the application. It’s easy to build now that all the parts are available, because it’s just an overgrown 3.5L with a different block, crank, pistons and cams. There are plenty of the 4.0L motors out there in cars that are worth fixing, so you should get some calls. The 3.6L Pentastar Meanwhile, the new 3.6L Pentastar motor that replaced all six of the “old” Chrysler V6 engines is very impressive. It’s available in almost everything Chrysler builds including their RWD cars, all of their minivans, the Jeep Grand Cherokee, the Dodge Durango and the Ram pickup and it performs well in all of them. In fact, it’s so versatile that the engine that’s in the pickup trucks is the same one that’s used in The counterweights on the late 4.7L crank are bigger because the rods and pistons are heavier. You can see the difference in the size and shape of some of them on the new crank on the right compared to the early one on the left. 42 March 2013 | EngineBuilder Circle 43 for more information Feature Updating the CHRYSLER ENGINES The heavy duty rod for the dual plug motor (right) is forged steel with a cracked cap and a tapered small end that has a press fit pin.

Now that we have updated all the Chrysler V6 motors, let’s take a look at a couple of the V8s, starting with the 4.7L engine that came with dual spark plugs in ’08. All of these engines are still either a VIN ‘N’ or ‘P’, depending on the year and the application. THE DUAL PLUG 4.7L V8 Chrysler updated the 4.7L with a new pair of heads that have slightly different intake ports and noticeably bigger exhaust ports that are squared off on the top along with a revised combustion chamber that has dual spark plugs, just like the Hemi. The dual plug 4.7L makes a very respectable 300 horsepower, so it’s become the standard engine for the Ram pickup. It appears that one long block fits everything from ’08 through ’12 according to the information we found on the Hollander interchange site and in the Chrysler parts book.

Chrysler has installed the 3.6L in nearly a third of the vehicles that they have produced since 2011 and it’s been nearly trouble free since day one. There were a handful that had phaser problems and a very small percentage that had a slight machining error that affected the heads according to my sources, but the engine has performed well with a minimum of problems in a wide variety of cars and trucks since the beginning. They’re all VIN ‘G’ motors and they all share the same short block, heads and cams, so they’re virtually identical as far as the rebuilders are concerned, but they have different intakes, sheet metal and accessories, depending on the application, so 44 March 2013 | EngineBuilder the complete engine assemblies aren’t always interchangeable, in spite of their simiThe cams for the dual plug 4.7L (in back) have powdered metal lobes larities. pressed onto a solid bar that's been machined for this application.

It’s the 53022033AA casting that has the three extra bolt holes on the driver’s side that were originally used to mount the front differential on the 4x4 Durango way back then. Con Rods The connecting rods are real, old time forgings instead of the powdered metal ones that are used in most engines today, but they have a cracked cap and there’s no notch for a tang! The small end is tapered like the one on the 3.5L/4.0L rod, but it has a Crankshaft Chrysler used an allnew crankshaft (look for “288AA” forged on the front counterweight) for the dual plug motor. The pistons and the rods are considerably heavier, so some of the counterweights are longer and they have square ends instead of the bull-nosed ones found on the original cranks. The early and late crankshafts can’t be interchanged without some serious modifications, so don’t mix them up. The dual plug engine uses the NGC computer so it still has the tone wheel with 32 notches. The beehive spring for the dual plug motor has a one piece, unitized, plastic base that incorporates a damper and includes the stem seal. The plastic base is starting to melt under the exhaust springs on our original cores, so you may have to buy some new springs for about $5 a piece. The lifter for the dual plug motor (right) is slightly different on the outside, but the real difference is the addition of a check ball inside the lifter to meter oil to the cam follower.

Chrysler machined the journals on a solid, steel bar along with some splines that were used to locate the powdered metal lobes that were pressed onto the bar. These cams are physically interchangeable with the old ones because the bore spacing is the same and the valves are all still in the same place, but we expected to see some differences in the new cams – until we ran them through the ‘Cam Doctor’ and discovered that they’re absolutely identical to the hollow ones in every spec and dimension.

It’s really an all new engine with a different block, crank, rods, pistons, cams, heads and timing set. The block is a 53021319DK casting and the crank is a 53021300BB. The heads appear to be identical, but one of them is a 53021616DD and the other one is a 53021616DE casting and Chrysler lists them separately, so there must be a difference of some kind. We don’t know much more about these engines except that there are five different cams including the one for the hybrid motor that was supposedly built in ’09. Here’s the list of all the different cams along with their applications: for “late intake closing,” just like the one that was used for the hybrid LS motors in the GM pickups. None of the cams are interchangeable, but they’re easy to tell apart because there’s an ID ring in front of the fifth journal that has a varying number of grooves that are machined in different locations so you can identify each cam by type and application, according to Chrysler. Be sure to use the right cam when you build one of these engines or you will have a comeback. The bad news is that they’re all VIN ‘T’ motors, so you will have to know the exact application and find out whether or not the vehicle has MDS or/and an “active intake” in order to supply the right engine. 1. VVT only with a high performance profile for the Challenger with a manual transmission. 2. VVT only for the 2500/3500 pickups with a profile that’s designed for the heavy-duty trucks. 3.

They didn’t build many of them so there isn’t even a part number for the cam in the parts book, but it’s probably a special cam that came with a unique phaser that was designed The 4.7L used three different cam followers that came with and without the oil hole in the socket. The late cams don't have oil holes in the lobes, so be sure to install the latest follower that has the oil hole to lubricate the cam. Conclusion So that’s the story. Chrysler has simplified their vehicles by eliminating three engine families since ’07 while adding the four cylinder “World Engines” along with the all new DOHC 3.6L V6 and updating both the 4.7L and 5.7L V8s with new technology that improved fuel economy, performance and emissions. And, there’s more to come, because they will have to continue to improve their engines with more new technology in order to meet the higher CAFE standards that are yet to come, so you can expect smaller engines with lightweight blocks, sophisticated heads, new rods and pistons, narrow rings, direct injection and a high tech valve train like MultiAir along with superchargers and turbochargers. With all that in mind, it will be interesting watch the evolution of the Chrysler DOHC family and their new four cylinder “Tigershark” engines along with the Hemi.` It’s time for everyone to “buckle up in lane two” as they say at the racetrack. ■ Doug Anderson is Manager of Technical Services for Grooms Engines, located in Nashville, TN.

The most effective way to upgrade an engine is to increase the cubic inches. Back in the day, most gearheads would look for performance by giving the engine an overhaul, which would include oversized pistons followed by some decent cylinder heads and a bigger carburetor. Then, they developed the art of swapping bigger crankshafts and connecting rods to achieve more stroke for more cubes. I remember when the Chevrolet The Raptor Tak k I n an age when kids would rather hot rod their computers than their cars, it’s kind of amazing that old fashioned hot rodding still exists – even thrives in today’s society. While computers certainly have their place, the younger generation is still looking for entertainment and thrills – whether captured in HD or in real life. And there are more ways than ever for people to get their kicks on a race track: from go-karts to golf carts, Indy cars to lawnmowers, diesel trucks to snowmobiles, the list goes on and on. It’s all about competition and who is in the lead. For crying out loud, it’s a race to see who can have the fastest smart phone! The awesome thing about computers and technology is the fact that the internal combustion (IC) engine continues to reach for higher plateaus. Over the past ten years, the IC engine has been resurrected to reach new heights of horsepower and torque – and it only keeps going. As soon as a new engine is released into the consumer market, hot rodders have figured out a way to make it faster.

You know as well as I do that we were living in the dark ages. Instead of creating new en- gine designs to be more emissions compliant, the manufacturers simply bolted on the emissions garb to existing power plants and killed all performance. It was like living in the dark ages, with no horsepower in sight and aftermarket offerings such as aluminum cylinder heads and custom pistons were nothing more than a dream. Such creativity is a far cry from what’s required today. Aftermarket companies now specialize in stroker kits for just about any application you can think of. The kits are complete rotating assemblies that are balanced and ready for installation. These stroker kits are not only available for yesterday’s classics, but also for today’s latemodel powerhouses. Aftermarket engine blocks are also available, completely machined and clearanced for bigger stroke applications and ready for the rotating assembly. Aluminum cylinder heads are now offered in many different engine combinations and if heads aren’t available (the latemodel Hemi, for example), then some aftermarket companies offer CNC porting for your castings. This means more efficient camshaft and valvetrain designs are available to get the most out of your stroker project, whatever your application may be.

In 2010, this truck debuted as an F150 with all of the features to be called a truly sophisticated off-road vehicle. Along with such necessities as wide body and fenders and 12” of suspension travel with unique wheels and awesome creature comforts came the introduction of the 6.2L Raptor engine. The engine, a modular design, includes some technological features that set the engine apart from earlier designs offered by Ford. The engine is a single overhead cam, variable valve timing design with a semihemi combustion chamber. Right out of Livernois developed a rocker brace system that is designed to improve valvetrain geometry and offer increased durability. the box, the engine produces 410 horsepower and 440 ft. lbs of torque. These are great numbers, so when looking at the pics of the truck or even possibly passing by one on the highway, could you possibly imagine any necessary engine modifications? Of course you could – you’re a car crazy gearhead like the rest of us! Even though the truck has only been in production for three years, it continues to grow in popularity and has become a vehicle of choice for those who prefer a hot rod truck instead of a car.

The block is fitted with ARP main studs with special modifications to the front main bearing for blower drive applications and modified thrust bearing for improved wear and durability. The cylinder heads are then prepped to undergo some major modifications. I always thought the cylinder heads from the factory were pretty good, but Livernois seems to have some added features which really bring them to life. First of all, the cylinder head is fully ported with a proven CNC program which brings head flow to 356 cfm @ .650” on the intake and 232 cfm @ .650” on the exhaust. They install a set of upgraded valve springs with special ground billet camshafts. Other improvements include a rocker brace system designed by Livernois along with cam phaser limiters for more variable valve timing control. To put these modifications into perspective, the conversion from the stock 6.2L Raptor to the stroked 6.6L version with 11:1 compression, results in 150 more rear wheel horsepower. Most of the Raptor builds at Livernois are done using the 9.5:1 compression version. As mentioned earlier, these modifications are for forced induction add-ons. In twin turbo applications, the 6.6L Raptor conversions can produce over 800 rear wheel horsepower. A raptor, of course, is a “bird of prey,” and the Raptor F150 was Ford’s answer to the demand for an off-road application. Produced to compete with the Chevrolet Z71 Silverado and Dodge Power Wagon, this unique vehicle has a very different Ford appearance and definitely offers all the character and power for off-road supremacy. From the factory, the trucks are equipped with Fox Racing shocks, massive skid plates, an electronic locking rear differential, a Torsen front differential, high performance all terrain tires, seven more inches of track width, front and rear cameras, and “Hill Descent Control.” Obviously, we’re not looking to help increase sales for Ford, but this article may give a perspective on what technology can do. If your racing customers were to be invited to upgrade their stock Raptor engines with some machine work and some parts changes, they could gain 150 rear wheel horsepower. This is why hot rodding has become so popular. Twenty years ago, such modifications would have been a major undertaking. Now, the technology lies at your fingertips. Technology has brought new designs, new machining processes and new parts built with better materials and tighter tolerances. And technology can help tune for maximum power and efficiency. Thanks to all these achievements, we can employ the new era of hotrodding into the cars of yesterday as well as the excitement of yesterday into the vehicles of today. Now we can enjoy drivability along with creature comforts such as air conditioning and power steering with power that would double what we could acquire twenty years ago. ■ Circle 55 for more information EngineBuilderMag.com 55 How To Use This Resource Guide 56 March 2013 | EngineBuilder CRANKSHAFT Eagle Cast King Uncoated 5.700 Eagle Forged, I-beam, Rod Ratio 1.52 5.700 LPC H-Beam Mahle/SRP Forged Keith Black 10.1:1 Hypereutectic Keith Black Steel, Straight GENERAL MOTORS Small Block Stroker Kits BEARINGS RODS PISTONS PINS RINGS Hastings Moly, Ductile Iron LPC Plasma Moly Admittedly, we couldn’t get everything in these charts as we’d like, however, this should give you a good idea of what kind of kits are available and from which suppliers. We have organized the data by manufacturer and then block type, whether it's a small block or big block or something else. GM’s LS platform, for instance, has it’s own section because, well, there are just so many variations. Our “Other” section includes mostly import kits but is hopefully a growing section to be filled with sport compact kits in the future. If you want to find a specific kit for, say, a Small Block Chevy 350, then you could look under the appropriate heading and scroll down the left hand column to find the stroker displacement you wish to build. We included as much information as we could fit on the page and sent forms out to every major engine parts supplier for their feedback. Of course, not everyone chose to participate and we didn’t want to make anything up for them. We also included sections in the form for identifying timing components, whether it was a timing chain, belt or gear included with the kit and the manufacturer. Unfortunately, this information was incomplete so it was not included. However, many stroker kits do come with timing sets and oil pans (also an incomplete section). We suggest that you select a kit and then call the supplier listed for further information on each of their kits. This information is as accurate as we could make it but there may be other features and components available. Furthermore, you may be able to swap out components for other brands if that is your preference, but, again, give your supplier a call to see what you can do with your kit selection. ■ MAX RPM PART NO.

Conley overcame the first setback with years of sheer determination. The second issue required using his Sunnen MB 1660 honing machine, abrasives and some expert honing advice. Today, the man for whom “perfection is almost good enough” has a business building his Stinger 609 V8, with a long backlog of orders from collectors and hobbyists around the world, and he credits honing as the process that helped him come up with a smokin’ hot product. Conley’s Stinger 609 is no toy or novelty, but a serious engine built for high performance and durability. Modeled on a Viper V10 and available in naturally aspirated or supercharged versions, the Stinger has a dry-sump, pressurized lubrication system, elec- tronic ignition, electric starter, split main and rod bearings, steel valve guides and seats.

The Stinger 609 is no toy or novelty, but a serious engine built for high performance and durability. It is modeled on a Viper V10 and available in naturally aspirated or supercharged versions. Genesis of The Stinger 609 Conley began pursuing his dream – with ample support from his wife – after completing his master’s degree and doing a five-year stint as a teacher. In 1996, his reputation led Chrysler to request that he build a quarter-scale Viper V10. Soon after, a full-size V10 engine arrived at his shop to be “reverse engineered” to the quarter-scale size. After five years of development, with the V10 ready to go into production, disaster struck, when his molds were destroyed in a foundry fire. More than $350,000 in molds and five years of time vanished. However, Conley retained the mold masters from the V10, and realized he had plenty of knowl- Circle 66 for more information 66 March 2013 | EngineBuilder Circle 65 for more information THIS ISSUE: PG 70 >> Business Savvy PG 72 >> NASCAR Performance PG 80 >> On The Web Perf. Notes edge to build on. With steely determination over a period of additional years, he carefully redesigned his tooling to produce V8 components, and thus was born the Stinger 609. about the nuances of crosshatch, including the proper angle and depth required to create valleys to retain the oil. “At the time, I did not associate Sunnen with a solution to the problem,” Conley said. “I was honing with the MB 1660, but came to learn my surface finish was too smooth. So, I got a very coarse, 80grit, 5-hardness J25 silicone carbide Smoke Gets In Your Eyes According to Conley, the first units of the Stinger engine burned oil so badly they filled a room with smoke in seconds. He discovered the problem was too much oil being pushed up into the cylinders, and though he did not realize it at the time, his honed cylinder surface was too smooth. “The problem was that the molecular size of oil does not scale down,” he explained. “I thought this was caused by the rings, and spent months assembling engines, making new liners, honing and decking the liners, re-designing the rings and pistons, and testing to no avail.” Digging deeper into the science of ring and cylinder design, he learned The parts can be made as small as needed – but oil molecules won’t scale down. The solution to blowby? Attention to surface finish on the cylinder walls. Circle 67 for more information EngineBuilderMag.com 67 Perf. Notes honing stone. This produced nice surface valleys for the oil to be retained, but I had not accounted for the surface peaks. After installing rings with an end gap of .003-.004˝ and running the engine, the end gap suddenly increased to .012˝, because the rings were abrading the peaks off the cylinder finish, and the oil issue returned. Bear in mind, we are using stepped cast iron rings only .062˝ thick, without an oil control ring because there's no space for one.” After consulting with his equipment supplier, Conley determined that plateau honing was the answer. Plateau honing – a second pass with a brush or milder abrasive – removes the surface peaks left by the initial pass. It creates a surface profile that resembles a series of plateaus, providing a much greater bearing area, while maintaining the cross- “The normally aspirated Stinger produces about 4.5 hp, while the supercharger version hits 9.5 hp at 10,000 rpm” hatch valleys for oil retention. “I once ran a set of new rings in a cylinder that had been plateaued and one that was not,” Conley added. “The plateaued cylinder had no ring wear after run-in. The end gap did change slightly, but this is probably cylinder wear rather than ring wear, because so much happens so fast in these small engines.” Honing Used On Many Bores Today, honing continues to be an important step in the creation of Conley’s quarter-scale beasts, and he attributes much of his honing knowledge to his equipment supplier. “I learned decades worth of information about honing from them,” he said. “Learning how to line hone an engine block straight and true was quite an achievement. We could not get the tandem cam and crank bores on the same centerline without this. Using a three stone mandrel, I can hold .001”, end to end, on a six-inch workpiece. After the investment cast aluminum block is machined and the main bearing is torqued down, we line hone the bores for the crankshaft and the camshaft. The 4140 camshaft rides on the T6 aluminum, just like a real Viper engine. The crank and cam bores are about .875” and .625” respectively. We machine the 7075 connecting rods and install a bearing insert that allows the engine to start dry, without oil pressure, and we experience no wear on the crank or con rods. The smallest bores we hone are the tops of the con rods – about .248” – and the piston pin bores. I stack a set of rods on a ground pin using the large end of the rod, then hone the pin bores to ensure they are all at the exact same height and straight.” Conley stresses he designs for longevity. “Our use of 6-bolt mains makes our lower almost bulletproof,” he said. “We also have crankcase ventilation and split keepers on the valves to keep them in place. Oil filtration is critical on a small engine, too. It’s amazing what comes out of the filter system. “ Conley sources the parts that he doesn’t create himself, including quarter-scale spark plugs from miniature model engine builder Paul Knapp in Payson, AZ, rings from Dave McMillan at D.A.M. Good Engineering in San Jose, CA and castings from Invest Cast, Inc. in Minneapolis, MN. “I’ve been very fortunate to find people who share my passion for creating these engines,” said Conley. “Bill Walker, Sr. at Invest Cast assured me that his group could cast the parts I needed, and they delivered.” In terms of output, the normally aspirated Stinger produces about 4.5 hp, while the supercharger version hits 9.5 hp at 10,000 rpm.

There is a definite amount of strategic planning, skill, and coordination that goes into creating a perfect direct mail campaign, but if you get it right, it can propel your business to new heights. You cannot just snap your fingers and produce an effective design and targeted mailing list, but I know a few tricks of the trade that can help you construct a winning campaign right from the beginning. That way you can forego the trial and error setbacks many of us in the marketing industry, myself included, experienced on the road to direct mail marketing expertise. I won’t lie to you; there are many nuances that go into creating a fullyoptimized postcard marketing campaign. HOWEVER, that’s not what we need to discuss right now. Instead, let’s focus on the Big Three; because once you know the Big Three, you can create excellent results with your postcards, even if you haven’t yet mastered the more nuanced strategies designed to wring every last cent out of your marketing investment. By nailing the Big Three, you will see big-time results from your marketing. Then, you can focus on finetuning later. The Big Three are: Size, Design and List. CONTRIBUTING EDITOR Joy Gendusa firstname.lastname@example.org J The size of your postcard directly and immediately affects the response to your mailing. Of course, there are many variables when comparing direct mail campaigns, but you would be hard-pressed to find someone who disagreed with the following statement: “A larger postcard is easier to see.” It is simply a fact. A large postcard IS easier to see than a smaller one, and that means more people will notice a large card, read it, and engage with your advertise- Postcard Size “What size postcard do I need?

What is the benefit of a bigger postcard anyway?” 70 March 2013 | EngineBuilder The size of your postcard directly and immediately affects the response to your mailing. There are many variables when comparing direct mail campaigns. ment than they would with a smaller card. Most direct mail postcard companies have options when it comes to the size of your card. If the company you choose doesn’t give you options, choose another company. Usually, your options will look like this: Small (4x6), Medium (5x8), and Large (6x11), though the names will vary. The size you need can be decided by answering these questions: 1. How much do other companies in your industry market? a. Not at all/I’m the only one (You can lean towards a smaller card) b. Light to Moderate Amount (Lean toward a larger card) c. Moderate to Heavy Amount (You need a large card) 2. Do your direct, local competitors also mail postcards? a. No (You can lean toward a smaller card b. Yes (You need a large card) 3. How much explaining does your offer require? a. Not that much/Easy to grasp (Smaller card is fine) b. A little background info (Medium should do the trick) c. A lot/Details are important (Go big or go home) My guess is that for machine shops, the answers are Bs across the board. Based on these results, my suggestion is a medium or large sized card. There is no use putting the effort into a card just to have it ignored because you wanted to save a little bit on printing. You are selling a larger ticket item/service, so a larger advertisement is in order. THIS ISSUE: PG 72 >> NASCAR Performance PG 73 >> Product Spotlights PG 80 >> On The Web Business Savvy Graphic Design In order to design a card that cuts through the noise and communicates your message to prospects, there are a few elements that you need to be aware of and include in the design; precisely, there are ten of them: 1. Clear Headline 2. Supporting Graphic 3. Color that Pops 4. Intriguing Sub-Headings on the back that lead into benefits 5. Benefits! 6. Enticing Offer 7. Business Name and Logo 8. Call to Action and/or expiration date for the offer 9. Contact Information – website, map, phone number 10. Return Address (You can find direct mail postcard samples at http://bit.ly/WMpw86) Elements 1, 2, and 3 are crucial to grabbing attention and immediately turning that attention into a decision to continue reading the postcard. If you fail to grab attention and generate in- terest, your card will be trash canbound. Elements 4, 5, and 6 are where you persuade the reader to take action. The sub-headings pull the reader into the body copy, which needs to be chock-full of customer-related benefits. Then you seal the deal with an offer they can’t refuse. Elements 7-10 give your prospect the information he needs to respond. Number 8, the call to action, is especially important because, believe it or not, most people won’t think to take action if you don’t ask them to. They are too busy already. Once you get these elements working together, you are ready to mail. But to whom? The Mailing List The final, and most crucial, of the Big Three is the mailing list. Even a great postcard is toast if you mail it to the wrong sort of people. You see, the mailing list defines the type of person who will be receiving your ad. That’s why it influences response more than any of the other factors. To get the perfect mailing list, you need to under- stand the type of person who is your “ideal prospect.” Does your shop cater to a specific clientele? Maybe higherend automobile engines? What about diesel truck engines? Whatever your ideal target market is, that is who you need to get a list of. The specificity of the lists you can obtain is astonishing, too. The trick is to know exactly the type of prospect you are looking for. So if you want to give your marketing a boost, just nail the Big Three. Postcards are proven to work. I have seen it over and over again for 55,000+ businesses. They work, and this is how to make them work for you. Now, go make 2013 your most profitable year yet! ■ Joy Gendusa is the owner and CEO of PostcardMania, a full-service postcard marketing company helping clients create turnkey marketing campaigns with graphic design, printing, mailing list acquisition and mailing services.
