The Classic 454 Big-Block topped with Aluminum Heads and Intake, Mated to a Stout 6-Speed Gearbox!

The Chevrolet Performance engineers started with the tough 454 HO and added a set of better flowing, lighter weight, oval-port aluminum cylinder heads to pick up 15 additional horsepower. Don’t worry though, that meaty torque is still there ? all 500 foot-pounds of it! It is all housed in the latest-generation block casting with four-bolt main caps that contain an all-forged rotating assembly for superior strength and durability. The ZZ454 is an affordable high-performance Big-Block Chevy ready to take your hot rod project to the next level.

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. The exterior case is similar in style to the T56 used in the fourth-generation F-body with stronger, high-capacity gear sets, input shaft and output shaft used in the Tremec TR6060. Kit includes shifter handle and Chevrolet Performance-logo ball-type shift knob to complete your install.
