GMP-19301294-KX - Fully Assembled GM ZZ5 350CID Turn-Key Crate Engine
This product may require vehicle validation(s) for proper fitment. Please contact us to confirm correct vehicle fitment and usage.
With more ZZZ through ZZ4 crate engines sold over the years than any other high performance crate engine, it only makes sense that Chevrolet Performance parts would continue to improve that successful family of engines.
The new ZZ5 uses the proven ZZ4 short block and adds to it the Fast Burn aluminum cylinder heads for 400 value packed horsepower. With value in mind, the ZZ5 uses stamped steel rocker arms and the same ZZ4 camshaft that powers thousands of hot rods. The ZZ5 is an excellent choice for the basis of a custom engine. Its strong forged steel crankshaft and forged powdered metal connecting rods have been proven to 500 horsepower. Value priced small-block power, great durability, easy power upgrades.
