ZZ572/620 Deluxe
The most powerful Big-Block street engine from Chevrolet Performance
Designed, engineered, tested, and backed by Chevrolet, the ZZ572/620 is the ultimate expression of Chevrolet Performance capability. We built the ZZ572 with huge 4.560-inch bores and add a forged 4.375-inch-stroke crankshaft. To make sure those cylinders are packed with every cubic inch worth of atmosphere, we use a camshaft with incredible 0.632/0.632-inch lift and254/254-degree duration specifications.
Chevrolet Performance delivers the ZZ575/620 Deluxe with an 850-cfm carburetor, HEI distributor, aluminum water pump, and distinctive orange power-coated valve covers that proudly proclaim the 572 legend.
