Features

• Premium alloy: Dart Aluminum blocks are cast from RMR cast Aluminum alloy for superior strength and integrity.

• Extended cylinder barrels for improved piston support.

• Four deck heights: 8.200” (302), 8.700” (stroker 302), 9.200” (351C) and 9.500” (351W) allow displacements up to 450 cubic inches.

• Siamesed cylinders: Standard 4.000” or 4.125” cylinders can be safely bored to 4.165” diameter. Ductile Iron sleeves and extra thick walls prevent cracking and produce excellent ring seal.

• Steel 4-bolt main bearing caps are standard. Three center caps have splayed outer bolts for maximum strength; rear cap uses standard one piece seal.

• Upgraded oiling system has been completely redesigned with a low restriction priority main oiling system with rear external oil pump feed.

• Dual crossovers allow oil flow to be metered with restrictors for roller lifter cams and/or roller rocker arms to reduce oil flow and windage.

• Reinforced head bolt bosses are blind tapped to prevent leaks and produce accurate torque readings. Extra thick decks prevent head gasket leaks.

• Parts kit included (Part# 32000032). Parts kits do not include cam bearings.

Dart blocks can be special ordered with a wide array of special machining options to suit your specific requirements.
