BIG BLOCK PERFORMANCE WITH TORQUE TO SPARE

When you're ready to step it up, its time for GM Performance Parts ZZ572 and its massive 620 Horsepower and 650lb.-ft. of torque! This is flat out, the baddest street Rat avaliable that still happily runs on pump gas. The ZZ572/620 features 572 cubic inches of pure big block and ships to your door in the coolest collection of orange, chrome and aluminium you've ever seen.

There are several custom designed components that make the ZZ572/620 the king of the street. It has a strong 4 bolt block that was created with a 4.560" bore just for the 572" displacement.

The 572 block is fortified with a forged crank, forged rods, forged pistons-everything was designed to offer you the ultimate big block experience. To feed all of those hungry cubes, we topped it off with a single plane intake manifold that has been port matched to the rectangular port aluminium heads. A custom hydraulic roller camshaft uses .632 inches of valve lift to lead the charge. We make no apologies if the loping, aggresive idle of this camshaft attracts attention.

The Deluxe ZZ572/620 comes complete from oil pan [with windage tray] to carburetor, including a 850-cfm Holley four barrel, HEI distributor, red spark plug wires, aluminium short style water pump and automatic transmission flex plate.

Its the ideal combination of big block parts, designed, validated to GMPP standards and tested in real world applications.
