Our Baddest Big-Block street engine backed by a stout 6-speed manual transmission!

Proving there is no replacement for displacement, the ZZ572/620 is the ultimate BBC crate engine. We build the ZZ572/620 with huge 4.560-inch bores and a 4.375-inch stroke to help it deliver 620 hp and a stunning 650 lb.-ft. of grunt. Strength comes from a brand-new, latest-generation block casting with four-bolt main caps and an all-forged rotating assembly, topped off with high-flow aluminum rectangular-port cylinder heads for tremendous airflow.

A hydraulic roller camshaft with 0.632/0.632-inch lift and 254/264-degree duration allows all that airflow in and out of the combustion chambers. 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.

It’s all backed by the T56 Super Magnum six-speed manual transmission for thrill of selecting your own gears and a double overdrive to make highway cruising a pleasure. These transmissions are rated to 700 lb.-ft. of torque and are brand new from the ground up. They use an extensively modified transmission case to prevent leaks under high-stress conditions and increase overall power-handling capabilities with stronger, high-capacity gear sets, input shaft and output shaft from the Tremec TR6060. Kit includes shifter handle and Chevrolet Performance-logo ball-type shift knob to complete your install.
