  • The Classic L88 427 Big-Block
    Updated for the 21st Century!

    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.
