ZZ572/620 Chevy Performance Crate Engine

620 hp @ 5,500 rpm / 650 lb.-ft. @ 4,500 rpm

 

Our Baddest Big-Block Street Engine!

Proving the adage there’s no replacement for displacement, the ZZ572/620 crate engine is the ultimate expression of Chevrolet Performance 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 620 hp and a stunning 650 lb.-ft. of grunt!

See GM engineering at its best! Strength comes from a brand-new, latest-generation 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 incredible 0.632/0.632-inch lift and 254/264-degree duration specifications optimizes the airflow volume enabled by the large-port heads.

Chevy Performance delivers the ZZ572/620 Deluxe crate motor with an 850-cfm carburetor, HEI distributor, aluminum water pump and distinctive orange powder-coated valve covers that proudly proclaim the 572 legend.
