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 can help enhance drivability – and performance!
Our engine assembly features our 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 flat-tappet 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 10.1:1 compression ratio.
Whether you’re building a ’69 COPO Camaro resto-mod tribute, a modified mid-year Corvette or a street-tire class winner, this heritage-inspired crate engine delivers the performance that built the Big-Block’s legendary reputation.
