Fits On/Installation Notes:

This GM Performance engine uses the ZZ4 short block and adds to it the Fast Burn cylinder heads for 385 horsepower. The Fast Burn uses stamped steel 1.5 rocker arms and the same camshaft as the ZZ4, but these heads are hungry for more. The Fast Burn is an excellent choice for the basis of a custom engine. Its forged steel crankshaft and forged PM connecting rods are proven to 500 horsepower.
