    The spirit of the ZL1 commemorated in our limited-edition crate engine. It's been 40 years since a few enterprising dealer-backed racers worked the loopholes of Chevrolet's COPO ordering system to create a handful of factory-built 427-powered supercars that weren't found in any brochure or order guide. And while their intent was to dominate the popular Super Stock drag racing classes, they touched off what would become one of the colorful chapters in the muscle car anthology. The special cars-two Corvettes and 69 Camaros-were equipped with an all-aluminum 427 engine dubbed the ZL1" that was largely similar in specification to the vaunted L88 427, but with an aluminum block that saved about 100 pounds off the cars' nose-heavy front-ends. The engine was officially rated at 430 horsepower, but the true output was closer to 500 horses. GM Performance Parts commemorates the ZL1 with the Anniversary Edition 427-an aluminum-block crate engine that mimics the original in spirit, but with design upgrades that make it a street-friendly option for COPO Camaro tribute projects, pro-touring street machines and ultimate-performance Shark" Corvettes. Our modern aluminum cylinder block has strength-enhancing design features, screw-in galley plugs and more. We've also elected to use a hydraulic roller camshaft, making for smoother street operation and greatly reduced maintenance. A 10.1:1 compression ratio allows the Anniversary Edition 427 to drink from today's gas pumps, too. An owner's kit included with each engine comes with a serialized number that matches the block and valve cover numbers.
