Dart applied all their years of experience in manufacturing aluminum cylinder heads to create the ultimate aluminum small-block. Working with leading engine builders, we incorporated features that make the Dart block the best choice for an all-out competition engine. With pressed in dry sleeves, the Dart aluminum small-block is light, strong, and affordable. We raised the camshaft and spread the oil pan rails to provide extra clearance for stroker cranks. With displacements up to 455 cubic inches (4.190" bore x 4.125" stroke), the Dart aluminum block is ideal for sprint cars, Modifieds, late-model stock cars, dragsters, and unlimited competition classes.Includes coated cam bearings, freeze plugs and dowels. Let us finish machine finish your block so when it arrives to you, it is ready to assemble.
