Perfect Foundation For A Pump-Gas Boulevard Shaker!
Proving the adage 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. They build the ZZ572/620 with huge 4.560-inch bores and a 4.375-inch stroke to help it deliver 621-horsepower and a stunning 645 lb.-ft. of grunt! Strength comes from a latest-generation tall-deck block casting with four-bolt main caps, forged steel crankshaft, forged steel H-beam connecting rods, forged aluminum pistons, while 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.
