The DIY foundation for big torque! 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 Cubic Centimeter combustion chambers and big, 2.25 Inch intake and 1.88 Inch exhaust valves.
