The Dart Aluminum small block is light, strong, and affordable. With displacements up to 450 cubic inches, the Dart Aluminum block is ideal for sprint cars, modifies, late model stock cars, dragsters, and unlimited competition classes.

With pressed-in dry sleeves, upgraded oiling and steel 4-bolt main caps, Dart’s Aluminum blocks have the features that Ford racers need to build powerful and reliable engines.


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

• 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 (PN 32000004).
