ZZ572/620 GM’S LARGEST MOST POWERFUL STREET ENGINE
The new ZZ572/620 is built around an all-new Gen VI tall deck
Bow Tie cylinder block. This all new race block 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! Equipped oil pan may not clear Chevelle and Camaro applications.
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.
A new GM tall deck single plane intake manifold and 850 CFM
Demon carburetor deliver enough air and fuel to make the
620 horsepower at 5500 RPM and 650 ft.lbs. of torque at
4500 RPM. Ignition is handled by a GM HEI distributor.
Pump gas friendly, massive torque and horsepower, all from
GM, the ZZ572/620 is for those who consider excess to be
barely enough.
Available in both long block and deluxe engine configurations.
