Description: OUR BADDEST BIG-BLOCK STREET ENGINE 19331581Proving 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. We build 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, 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.TECH SPECSPart Number: 19331581Engine Type: Chevy Tall-Deck Big-Block V-8Displacement (cu in): 572Bore x Stroke (in): 4.560 x 4.375Block (P/N 19212195): Cast-iron with 4-bolt main capsCrankshaft (P/N 88961554): Forged steelConnecting Rods (P/N 88962926): Forged steel, shot peenedPistons (P/N 88962925): Forged aluminumCamshaft Type (P/N 19210721): Hydraulic rollerCamshaft Lift (in): .632 intake / .632 exhaustCamshaft Duration (@.050 in): 254° intake / 264° exhaustCylinder Heads (P/N 19331429): Aluminum rectangular port, 118cc chambersValve Size (in): 2.250 intake / 1.88 exhaust; stainless steelCompression Ratio: 9.6:1Rocker Arms (P/N 19210726): Aluminum roller styleRocker Arm Ratio: 1.7:1Recommended Fuel: Premium pumpIgnition Timing: 36° Total at 4,000 rpmMaximum Recommended rpm: 6,000Balanced: Internal This long block assembly is based on the ZZ572/620 Deluxe and includes the cylinder heads, oil pan, front cover and flexplate.
