ZZ502 Base Crate Engine - 502HP

The ZZ502/502 Base is a great foundation for the builder who wants the super strong bottom end and high-flow aluminum oval-port cylinder heads. A set of high-flow aluminum oval-port cylinder heads and a hydraulic roller camshaft designed to support low-rpm torque production enable it to hit the 500 lb.-ft. mark by approximately 2,500 rpm and hold it above the mark until around 5,000 rpm. Features a latest-generation block casting with four-bolt main caps and an all forged rotating assembly for exceptional strength and durability. It is rated at 508 horsepower and 580 lb.-ft. of torque when it is finished with Chevy’s aluminum intake manifold P/N 12363406 and Holley 870-cfm carburetor P/N 19170094.
