Chevy Aluminum Billet Small Block |
|
The advantages of Dart's billet block technology are also available to small-block racers. Continuous increases in power have made the conventional Chevy small-block design marginal in high-output applications such as sprint cars and off-road trucks. Dart's new 4.500" bore center billet aluminum small-block solves the shortcomings of OEM-based designs.
Increasing the small-block V-8's bore centerline dimension from 4.400" to 4.500" allows substantial increases in cross-sectional area in the highly stressed bottom end and provides more material around the cylinders to enhance ring seal. The camshaft is raised to provide clearance for long-stroke rotating assemblies and to improve valvetrain dynamics with shorter pushrods. The new R07-style head bolt pattern is available.
