Description

Dart’s Race Series Aluminum big block is based on the Chevrolet big block V8 design, with added features like increased deck height and a raised cam location.

The camshaft is raised .400″ above the stock location to increase clearance for the connecting rods and crankshaft counterweights. The main oil gallery is located alongside the camshaft tunnel to eliminate interference with the crank assembly.

Advanced engineering makes Dart Aluminum big blocks the choice for serious competition.
