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. Chevrolet Performance builds the ZZ572/620 with huge 4.560-inch bores and a 4.375-inch stroke to help it deliver 621 hp and a stunning 645 lb.-ft. of grunt! Strength comes from a latest-generation tall-deck block casting with four-bolt main caps and an all-forged rotating assembly, while high-flow aluminum rectangular-port cylinder heads with massive 310cc intake passages, 1.88 inch raised exhaust ports and 118cc combustion chambers process tremendous airflow. A hydraulic roller camshaft with an impressive 0.632/0.632-inch lift and 254/264-degree duration specifications optimizes the airflow volume enabled by the large-port heads.

• Clutch linkage boss is now drilled and tapped. When using cast-iron exhaust manifolds, lower head bolts may need to be replaced with bolts with shorter heads, for clearance
• Requires addition of starter and fuel pump (not included)
• Gen VI tall-deck block has machined mechanical fuel pump boss
• Comes with a 14" automatic transmission flexplate. Requires internally balanced flywheel for manual transmission applications
• Not intended for marine applications
