    Chevrolet Performance's ZZ502/502 is one of the industry's benchmark crate engines, offering excellent value with a proven combination of performance that is suitable for the street or strip. With more than 500 horsepower and 567 ft/lbs of torque, it demands your full attention and a chassis that is strong enough to harness its frame twisting power.

    All ZZ502 crate engines are manufactured with GM's updated cylinder block casting that is stronger and better supports high-performance applications. A forged crankshaft, along with forged rods and pistons, anchors the bottom end, while our popular oval-port aluminum heads offer excellent airflow characteristics. Torque tops the 500-lb-ft mark by approximately 2500 rpm and doesn't dip below it until about 5000 rpm.

    The ZZ505/502 Deluxe package comes complete from the oil pan to the carburetor, including an HEI distributor, plug wires, starter, water pump, balancer, and an aluminum intake topped with a Holley 870-cfm four-barrel.
