The most powerful Big-Block street engine from Chevrolet Performance

The ZZ572/620 is the ultimate expression of Chevrolet Performance’s engineering capability.

We build 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 centimeter’s worth of atmosphere, we use a camshaft with incredible 0.632/0.632-inch lift and 254°/264° duration specifications.

Aluminum rectangular-port heads with 310-cc intake passages complement the airflow capability offered by the big-bore bottom end. They also feature 118-cc raised exhaust ports and 118-cc combustion chambers. The valves are big, too — measuring 2.250 inches on the intake side and 1.880 inches on the exhausts.

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

For the builder who wants the foundation of this Big-Block powerhouse, but wants to finish it with the induction system of his choice, we offer the ZZ572/620 Base engine P/N 12498792. It comes with the bottom end fully assembled — including the forged crankshaft, rods, and pistons — along with the unique 0.632-inch-lift roller camshaft.
