ZZ572/720R …AND THE R STANDS FOR RACE!
Engineered by GM Performance Parts and GM Racing
exclusively for sportsman racers, the new ZZ572/720R 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 Hbeam
rods, and forged aluminum pistons with full floating
wrist pins. Plasma moly piston rings are standard is the
screened and louvered windage tray. GM’s first purpose built
drag race engine is filled with hard core race parts for hard
core performance and long term durability.
The redesigned rectangular port aluminum cylinder heads
result in a race gas only 12 to 1 compression ratio. A solid
roller cam with 0.714 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
valve train.
A new GM tall deck single plane intake manifold and 1095
CFM King Demon carburetor deliver enough air and fuel to
make the 720 horsepower at 6250 RPM and 685 ft.lbs. of
torque at 4500 RPM. Ignition is handled by a multiple spark
discharge ignition. And an SFI approved torsional damper is
installed at the factory. Out of the crate and into your race car
– it’s just that simple.
Race gas fueled, high revving horsepower, all from GM, the
ZZ572/720R is the engine that will get you down the track
consistently, pass after pass, season after season.
Available in both short block, long block and deluxe engine configurations.
