Drop some performance into your Street Rod, Muscle Car or Truck with these genuine Chevrolet Performance engines! All Chevrolet Performance engines include a 24 Month 50,000 mile warranty.  If you’ve never experienced the ZZ502/502, you simply don’t know what Big-Block power is all about. With more than 500 horsepower and 575 lb-ft of torque, it demands your full attention and a chassis that is strong enough to harness its gut-tugging twisting power. Chevrolet Performance Parts’ 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. And now, 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, anchor the bottom end, while GMs 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; and includes an HEI distributor, plug wires, starter, water pump, balancer and an aluminum intake topped with a Holley 870-cfm four barrel.
