Chevrolet Performance engineers matched the engines and transmissions for optimal performance and durability, so you can wring out every horsepower from them with total confidence! Designed for retrofit installations in older vehicles, for easier and quicker installation and operation without the need for guessing which parts will work with your combination.
The convenience of a crate engine, the assurance of factory validate performance and the value of an inclusive package - that's what you get with Chevrolet Performance's Connect & Cruise crate powertrain systems.

Each kit delivers a fully assembled crate engine, transmission and the installation kit to get it all running in your project vehicle - including the flywheel, clutch disc, pressure plate, hydraulic throw-out bearing (lines and master cylinder not included), fasteners and instruction sheets. Chevrolet Performance engineers matched the engines with their respective transmissions, ensuring they are up to the task of channeling big power with absolute dependability.

The engineers did all the hard work of designing and calibrating perfectly matched powertrain systems - and they covered them with a 24-month/50,000-mile limited warranty.

ZZ427 427ci, 480HP / 490TQ Engine
Between 1967 and 1969, the legendary L88 was the ultimate expression of Chevy's Big-Block power, combining a rigid iron cylinder block with lightweight aluminum cylinder heads and a single four-barrel carburetor. That raspy rat engine was rated at 480 horsepower, although the figure was generally thought to be on the conservative side. It powered some of the most storied cars in high-performance history.

Chevrolet Performance has recreated that classic Big-Block combination in the Z427/480 - including the 480 horsepower rating (and it just might be a little on the conservative side, too). Like the original, it features a forged steel crankshaft and high-flow, oval-port aluminum cylinder heads. They upgraded the camshaft from the original's mechanical flat-tappet design to a smoother hydraulic roller, which delivers great drivability characteristics and a broader rev range. A 10.1:1 compression ratio means it will perform great on pump gas, too. The engine's top half is the same as the Limited Edition Anniversary 427; the intake is a matching high-flow oval port aluminum piece. With 490 ft/lbs torque and a conservative 480 HP rating, this is still one of the best crate engines for nearly any big block application!

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 engine that delivers the performance that built the Big-Block's legendary reputation.
