We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited warranty.

Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!

Big Block Performance with Big Displacement

Proving the adage that there’s no replacement for displacement, the ZZ572/620 is the ultimate expression of Chevrolet Performance’s engineering capability, wrapped up in a soul-stirring combination of performance and attitude. Chevy builds the ZZ572/620 with huge 4.560-inch bores and a 4.375- inch stroke to help it deliver 621 hp and a stunning 645 lb.-ft. of grunt!

Strength comes from a latest-generation tall-deck block casting with four-bolt main caps and an all-forged rotating assembly. High-flow aluminum rectangular-port cylinder heads with massive 310cc intake passages, 118cc raised exhaust ports and 118cc combustion chambers process tremendous airflow. A hydraulic roller camshaft with an impressive .632/.632-inch lift and 254/264-degree duration specifications optimizes the airflow volume enabled by the large-port heads.

Chevrolet Performance delivers this Big-Block with an 850-cfm carburetor, HEI distributor, aluminum water pump and distinctive orange powder- oated valve covers that proudly proclaim the 572 legend.
