Description

It’s simple: We offer the ZZ502/502 Base crate engine for builders who want the super-strong bottom end and high-flow aluminum oval-port cylinder heads, but also want to finish the engine their way.
The ZZ502/502 Base engine uses our new cylinder block casting that is stronger and better suited to high-performance combinations. A forged steel crankshaft, forged rods, and forged pistons form the reciprocating assembly, with a smooth-operating hydraulic roller camshaft delivering big 0.527/0.544-inch lift. The lightweight aluminum heads boast 110-cc combustion chambers and big, 2.25-inch intake and 1.88-inch exhaust valves.
We rate the ZZ502/502 Base engine at 502 horsepower and 567 lb-ft of torque when it is finished with Chevrolet Performance aluminum intake manifold (P/N 12363406) and Holley 870-cfm carburetor (P/N 19170094). NOT INCLUDED.
