Chevrolet Performance 19331583 ZZ572/620 Deluxe Crate Engine
ZZ572/620 Deluxe Crate Engine
GM's Biggest, Baddest Street Engine!
Proving the adage that there is no replacement for displacement, this one is the ultimate expression of Big-Block capability. The ZZ572/620 is built around huge 4.560-inch bores and a 4.375-inch stroke to help it deliver 621 hp and 645 lb.-ft. of torque! Strength comes from the latest-generation tall-deck block with four-bolt main caps and an all-forged rotating assembly, while high-flow aluminum rectangular-port cylinder heads with massive 310cc intake passages, 118cc raised exhaust ports and 118cc combustion chambers provide tremendous airflow. An impressive hydraulic roller camshaft optimizes the airflow volume enabled by the large-port heads.
As a Deluxe package, Chevrolet Performance delivers this 572 with an 850-cfm carburetor, HEI distributor, aluminum water pump and distinctive orange powder-coated valve covers that proudly proclaim the 572 displacement.
