When GM Performance Parts engineers sat down to design the ZZ 572/720R, it was with the directive from GM to build something nasty. We think they accomplished that with the ZZ 572/720R Crate Engine. With a resounding 720 horsepower and 685 lb/ft of torque, this is the most powerful big-block crate engine ever offered by GM Performance Parts.

GMPP took the ultra-popular ZZ 572/620 pump gas street engine and added 12:1 compression pistons, a hotter camshaft and GM rectangular-port aluminum Bowtie heads with stiffer valve springs to work with the new cam. The block is the Gen VI tall-deck Bowtie block which was designed for the 572" application. The solid roller camshaft is a .714" lift magic maker that aggressively feeds the air/fuel mixture into the hungry, high-squeeze, stroker big-block.

Our ZZ 572/720R is rated at 720 horsepower @ 6250 rpm and 685 lb/ft of gut-wrenching torque @ 4500 rpm. The ZZ 572/720R Crate Engine is built with a 4340 forged steel crankshaft, shot-peened forged steel rods, forged aluminum pistons with full-floating wrist pins, stiff dual valve springs, and a louvered oiling windage tray. The ZZ 572/720R Turn Key Crate Engine ships to you with a 1090 cfm Demon four-barrel carburetor, tall-deck single-plane intake manifold, HEI distributor, aluminum short-style water pump and 8mm spark plug wires. Distinctive "572" cast aluminum valve covers complete the package. All you need is a high torque starter to crank it up.

Installation Notes:

Clutch linkage boss is cast and machined in block, but must be drilled and tapped. When using cast iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance.

Requires addition of starter, ignition coil and fuel pump.

Gen VI tall-deck block has machined mechanical fuel pump boss.

Requires internally balanced flywheel for manual transmission applications.

Designed for pre-1978 street vehicles or any off-road vehicle.

Not intended for marine applications.

Tech Note: The ZZ 572/720R carries a recommended fuel rating of 110 octane race gas.

Tech Note: No warranty applies to the ZZ 572/720R Crate Engine.
