This 1967 Chevelle has a great patina look — it’s not too nice to drive to the grocery store, but it’s way more solid than your average beater.

In the process of attempting to prove you can have just as much fun without a show car paint job, the guys at Muscle Car Review wanted to inject as much fun and performance as possible into the project without disturbing it’s barn-fresh good looks.

Chevrolet Performance ponied up a Chevrolet Performance ZZ427 – 480 HP big block crate engine for the project, which quickly recieved a weathering treatment and looks like its always been in the car.

About the Chevrolet Performance ZZ427 – 480 HP Crate Engine

A modern take on the classic L88 engine

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!

Our 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.

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.
