Engine - GM (19433160)
A DIY FOUNDATION FOR BIG TORQUE!
We offer the ZZ502/502 Base crate engine for the builder who wants the super-strong bottom end and high-flow aluminum oval-port cylinder heads, but also wants to finish the engine his or her way. It's a great foundation and it's up to you to make the most of it!
Like our complete ZZ502/502 Deluxe crate engine, 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. It also features a latest-generation block casting with four-bolt main caps and an all-forged rotating assembly for exceptional strength and durability.
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
Chevrolet Performance.
