Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!

NOTE: All components, engine, transmission, controllers and installation kits (where applicable) are ordered and delivered separately.

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. Chevy Performance engineers have recreated that classic, raspy rat engine, but with updated components that can help enhance drivability?and performance!

This engine assembly features Chevy’s 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.
