Chevrolet Performance ZZ572/720R Deluxe Long Block Crate Engines 19331585

Chevrolet Performance's ZZ572/720R is a race-tuned big block built from 572 cubic inches of cast iron and aluminum. Torque peaks near 685 lb-ft, landing at 4,500 rpm, while horsepower climbs to 720 by the time the engine reaches 6,250 rpm. A 12.0:1 compression ratio and solid roller camshaft put this well beyond street-tune territory, and the maker specifies a minimum of 110 octane race fuel to run it as built. What ships on this Deluxe long block A Holley 1150 CFM carburetor and a high-flow intake manifold come bolted on, with the distributor, oil pan, water pump, and harmonic balancer already in place, plus a timing cover and valve covers. The solid roller valvetrain is built for aggressive, high-rpm duty rather than daily-driver manners. What you still need to add A flywheel, flexplate, air cleaner, and wiring harness are not included, so plan those purchases separately based on your transmission and ignition setup. Because this engine is tuned for 110-octane fuel and extreme compression, it is not a pump-gas combination, and professional installation and a proper break-in are worth budgeting for before it ever sees the track. Q: Can I run this on pump gas? No, Chevrolet Performance specifies a minimum of 110 octane given the 12.0:1 compression ratio. Q: Does it include the carburetor? Yes, a Holley 1150 CFM carburetor ships installed along with the intake manifold.
