A MODERN TAKE ON THE CLASSIC L88

The L88 427 was the ultimate expression of Chevy’s production Big-Block power, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single, four-barrel carburetor. Our engineers have recreated that classic, raspy rat engine, but with updated components that enhance drivability – and performance! The engine assembly features the latest-generation block casting with four-bolt main caps, an all-forged rotating assembly for exceptional strength and durability, and a hydraulic roller camshaft instead of the original L88’s flattappet cam, 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.
