Nothing is quite as satisfying as building your own high-performance big-block. That’s why GM Performance Parts offers the entire ZZ502 engine as a kit. Every part is engineered to work together to deliver 502 horses! Kit includes aluminum oval-port heads, forged steel crank and rods, and forged aluminum pistons. It also includes a hydraulic roller cam, valve train and valve covers. You need to add an intake manifold, carburetor, water pump, distributor and spark plug wires - all available from your GM Performance Parts dealer.

NOTE: Designed for pre–1978 street vehicles or any off-road vehicle. Not intended for marine applications.
