QUALITY STRENGTH PERFORMANCE SINCE 1981<br />
QUICK INFO >>><br />
The Dart Aluminum small block is light, strong, and<br />
affordable. With displacements up to 450 cubic<br />
inches, the Dart Aluminum block is ideal for sprint<br />
cars, modifies, late model stock cars, dragsters,<br />
and unlimited competition classes.<br />
With pressed-in dry sleeves, upgraded oiling<br />
and steel 4-bolt main caps, Dart’s Aluminum<br />
blocks have the features that Ford racers need<br />
to build powerful and reliable engines.<br />
FEATURES<br />
RACE SERIES - ALUMINUM<br />
SMALL BLOCK FORD<br />
CAST ALUMINUM ENGINE BLOCKS<br />
• Premium alloy: Dart Aluminum blocks are cast from RMR cast Aluminum<br />
alloy for superior strength and integrity.<br />
• Extended cylinder barrels for improved piston support.<br />
• Four deck heights: 8.200” (302), 8.700” (stroker 302), 9.200” (351C) and<br />
9.500” (351W) allow displacements up to 450 cubic inches.<br />
• Siamesed cylinders: Standard 4.000” or 4.125” cylinders can be safely bored<br />
to 4.165” diameter. Ductile Iron sleeves and extra thick walls prevent cracking<br />
and produce excellent ring seal.<br />
• Steel 4-bolt main bearing caps are standard. Three center caps have splayed<br />
outer bolts for maximum strength; rear cap uses standard one piece seal.<br />
• Upgraded oiling system has been completely redesigned with a low<br />
restriction priority main oiling system with rear external oil pump feed.<br />
• Dual crossovers allow oil flow to be metered with restrictors for roller lifter cams<br />
and/or roller rocker arms to reduce oil flow and windage.<br />
• Reinforced head bolt bosses are blind tapped to prevent leaks and produce<br />
accurate torque readings. Extra thick decks prevent head gasket leaks.<br />
• Parts kit included (PN 32000004 - see page 118).<br />
