621 HP @5400 RPM
645 LB-FT @4200 RPM
Proving the adage there’s no replacement for displacement, the ZZ572/620 is the ultimate expression of Chevrolet Performance’s engineering capability.
The ZZ572/620 Deluxe is a powerful Big-Block street engine, combining 621 horsepower with legendary 572 style. Matched to either the heavy-duty T56 Super Magnum 6-speed manual or a 4L85-E 4-speed automatic in a complete, convenient Connect & Cruise package, its instant street cred is just an easy installation away. The ZZ572/620 is built with huge 4.560-inch bores and a 4.375-inch stroke. Strength comes from a latest-generation tall-deck block casting with four-bolt main caps and an all-forged rotating assembly.
