GM Big Block ZZ572 620 Deluxe Engines

572 cu in







Big-block performance with torque to spare.

When you’re ready to really step it up, it’s time for the GM Performance Parts ZZ572 and its massive 620 horsepower and 650 lb.-ft. of torque! This is flat-out, the baddest street Rat available 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 aluminum 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 rectangularport aluminum heads. A custom, hydraulic roller camshaft uses .632-inches of valve lift to lead the charge. We make no apologies if the loping, aggressive idle of this camshaft attracts attention.

The Deluxe ZZ572/620 comes complete from oil pan (with windage tray) to carburetor, including an 850-cfm Holley four-barrel, HEI distributor, red spark plug wires, aluminum short-style water pump, and automatic transmission flexplate. It’s the ideal combination of big-block parts—designed, validated to GMPP standards, and tested in real world applications.



The ultimate hot rod starting point Pump gas drag racing—just add spray Wake up the neighborhood—anytime! Only install if you want to be the biggest dog on the porch
