The new ZZ572/620 is built around an all-new Gen VI tall deck Bow Tie big block. This all new engine is filled with a forged 4340 steel crank with 4.375 inch stroke, shot peened, forged 4340 H-beam rods, and forged aluminum pistons with full floating wrist pins. Hard core race parts for hard core long term durability!

The redesigned rectangular port aluminum cylinder heads result in a pump gas friendly 9.6 to 1 compression ratio. A hydraulic roller cam with 0.632 inch lift actuates the stainless steel valves. And, of course, hardened chromemoly retainers, roller rocker arms, and dual valve springs are used to complete the valvetrain.
