The DIY foundation for big torque Its 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 508 horsepower and 580 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). The other parts you need to complete the engine including chrome dress-up parts are available from your dealer and chevrolet.com/performance.com. The ZZ502/502 Base is a great foundation. Its up to you to make the most of it.
