ZZ502 Chevy Performance Base Crate Engine

508 hp @ 5,200 rpm / 580 lb.-ft. @ 3.600 rpm

The Chevrolet Performance 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 hp and 580lb.-ft. of torque, it demands your full attention and a chassis that is strong enough to harness its frame-straining twisting power.

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 Karlperformanceparts.com

Thanks to the Chevy combination of high-flow aluminum oval-port cylinder heads with 2.25/1.88-inch valves and a hydraulic roller camshaft designed to support low-rpm torque production, this torque monster tops the 500 lb.-ft. mark by approximately 2,500 rpm and doesn’t dip below it until about 5,000 rpm. It also features a brand-new, latest-generation block casting with four-bolt main caps and an all-forged rotating assembly for exceptional strength and durability.

Nothing is quite as satisfying as building your own high-performance Big Block. The GM ZZ502/502 Base crate motor package includes includes the partial engine assembly, cylinder heads, valvetrain and valve covers. Every part is engineered to work together to deliver 502 horses!
