ZZ502 Deluxe

SKU: 19433162

Our most popular Big-Block crate engine for the street and the strip


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 508 horsepower and 580 lb-ft of torque, it demands your full attention and a chassis that is strong enough to harness its frame-straining 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.


Our 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.


We’ve taken care of the engine’s details. You need to make sure your car can handle the ZZ502/502.
