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. GM engineers have recreated that classic, raspy rat engine in the Chevrolet Performance ZZ427/480 crate engine, but with updated components that enhance drivability ? and performance!

This Chevy 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 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 10.0:1 compression ratio.

Whether you’re building a ’69 COPO Camaro resto-mod tribute, a modified mid-year Corvette or a street-tire class winner, the ZZ427/480 is the heritage-inspired crate motor that delivers the performance that built the Big Block‘s legendary reputation.
