CRATE ENGINES CIRCLE TRACK
Engine CT350 19258602 350 hp @ 5,000 rpm
390 lb.-ft. @ 3,800 rpm
GMPP’s most economical Circle Track crate engine! GM Performance Parts’ CT350 delivers 350 horsepower from a classic 350 cubic-inch combination. It’s just the thing budget-conscious racers can depend on for competitive performance and low-maintenance durability. The CT350 is based on the popular 350 HO high-performance street crate engine, including a stout four-bolt-main block and Vortec-style iron cylinder heads. The Vortec heads and unique dual-pattern camshaft help deliver more than 300 lb.-ft. of torque at 2,000 rpm and hold it above that mark through 5,500 rpm – it peaks at 390 lb.-ft. at 3,800 rpm. With that much pulling power, you can hold a gear longer, keeping the engine in its sweet spot for quicker laps. We complete the CT350 with an 8-quart circle track racing oil pan, balancer, HEI distributor and an aluminum high-rise, dual-plane intake manifold. Add your carburetor, starter, spark plugs, wires and water pump – all available at gmperformanceparts.com – and you’ll be ready to roll into the winner’s circle!
INSTALLATION NOTES • Requires addition of carburetor, starter, water pump, plug wires and exhaust system (not included) • Requires an externally balanced flywheel (not included). See page 165 for flywheel selection • The 8-quart Circle Track oil pan is 8 inches deep at the sump. It will clear most GM rear-steer chassis with stock engine location
