    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 small 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.


    HT383 Engine
    Do you have a pre-1980 GM truck with a tired Small-Block? Forget the rebuild and take your trusty truck's capability to the next level with this big-torque HT383 crate engine. The extra displacement and unique parts are designed to build a wide, flat torque curve that maintains at least 400 ft-lbs of torque between 2500 and 4000 rpm. The 323 horsepower and 444 lb-ft of torque is power you simply won't get with a stock-type rebuild.

Equipped with a forged steel crankshaft and a smooth hydraulic roller camshaft, and topped off with a set of cast-iron Vortec cylinder heads. The 9.1:1 compression ratio is perfect for regular gasoline at all altitudes and engine loads.
    The HT383 is delivered with an aluminum intake manifold that makes it ready for you to swap over the components and accessories from your tired engine. It's also backed by a 24-month/50,000-mile limited warranty.
