    When it comes to performance innovations that save time, money and guesswork, Chevrolet Performance once again leads the way!

    Chevrolet Performance pioneered the concept of crate engines more than four decades ago, and continues to lead the industry with their unprecedented Connect & Cruise crate powertrain systems - factory-engineered engine and transmission combinations that include all the electronic control modules, wiring harnesses and other key components.
    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! The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation and operation without the need for third-party tuning.
    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 brand-new, fully assembled crate engine, a brand-new or remanufactured electronically controlled overdrive transmission, and the electronic transmission control module to get it all running in your project vehicle.
    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 engine is traditional Big-Block Chevy design that was a staple for decades in rear wheel drive production-vehicles. The connect & cruise systems' unique SuperMatic transmission controllers is designed to work with the carbureted engine for a seamless, "plug-and-play" installation that is quick, easy and intuitive. Detailed instructions outline all the necessary steps.
    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.


    ZZ427/480 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. Chevrolet engineers have recreated that classic, raspy rat engine, but with updated components that enhance drivability and performance!
    This 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 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 10.0:1 compression ratio.
    The engine package includes a water pump, balancer, 14-inch flexplate, dual-plane intake manifold, 770-cfm Holley carburetor, and a HEI-style distributor with spark plug wires. Whether you're building a 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.
