A Modern Version of the L88 with Six-Speed Fun!
The L88 427 was the ultimate expression of Chevy’s Big-Block power back in the day, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single four-barrel carburetor. Our engineers have recreated that raspy rat engine feel with the ZZ427/480, and they did it with updated components that enhance drivability – and performance!
The ZZ427 features the latest-generation block casting with four-bolt main caps, an all-forged rotating assembly, and a hydraulic roller camshaft for greater drivability and a broader performance range. It also features aluminum oval-port cylinder heads with 2.19/1.88-inch valves and a pump-gas-friendly 10.0:1 compression ratio. It all adds up to 480 hp at 5,800 rpm and 490 lb.-ft. at 3,800 rpm!
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. Above Added: Thu June 13, 2019, 11:47 am PST
