Fast Burn 385/The Evolution of America's Favorite Crate Engine
P/N 12496769
With more ZZZ through ZZ4 crate engines sold over the years than any other high performance crate engine, it only makes sense that GMPP would continue to improve that successful family of engines. The new Fast Burn uses the proven ZZ4 shortblock and adds to it the Fast Burn cylinder heads for 385 value packed horsepower. With value in mind, the Fast Burn uses stamped rocker arms and the same ZZ4 camshaft that powers thousands of hot rods. The Fast Burn is an excellent choice for the basis of a custom engine. Its strong froged steel crankshaft and forged powdered metal connecting rods have been proven to 500 horsepower. And its Fast Burn cylinder heads are hungry for a little more cam. 430 horsepower at 6000 rpm is achievable by adding the HOT cam and 1.6 self aligning rocker arms.
