Supercharged Power from the C7 Corvette Z06! 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. Each kit delivers a fully assembled crate engine, transmission, electronic control module, and the engine control hardware to get it all running in your project vehicle - including the mass airflow sensor, oxygen sensors and even the special throttle pedal for the engines' electronic throttle bodies. 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 controller is specially calibrated to run the engine without some of the production-vehicle features that aren't required in an older vehicle. That means no "trouble" codes and no need for third-party tuning, "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. LT4 Supercharged 376ci / 6.2L, 650HP / 650TQ Engine The LT4 is based on the same Gen V Small-Block architecture as the LT1 engine, with several unique features designed to support its higher output and the greater cylinder pressures created by forced induction. They include Rotocast A356T6 aluminum cylinder heads that are stronger and handle heat better than conventional castings, lightweight titanium intake valves and stronger forged aluminum pistons. Chevrolet Performance's LT4 crate engine is rated at 650 horsepower and 650 lb-ft of torque, and it is offered with a wet-sump or dry-sump oiling system. Engines with the dry sump oiling system, you'll need to supply the external oil supply and oil lines to the engine, but the rest of the assembly is fully dressed, including the supercharged manifold assembly with injectors and electronically controlled throttle body, and exhaust manifolds.

When it comes to performance innovations that save time, money and guesswork, Chevrolet Performance once again leads the way!
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.
As the heart of the Corvette Z06, the supercharged LT4 6.2L SC is the most powerful engine ever offered in a regular-production Chevrolet. It features a more-efficient, more-compact 1.7L Eaton R1740 TVS supercharger, which spins at up to 20.000 rpm. That's enough to generate more than 9-pounds of boost and help produce 650 horsepower and 650 lb.-ft. of torque.
A precisely calibrated engine control module is essential to making your fuel-injected LT engine perform in your older vehicle - and Chevrolet Performance is your source for controllers that are designed for easy, "plug-and-play" installation and, in most applications, no need for third-party tuning adjustments.
Unlike production controllers that may or may not come with a used engine, these controllers are calibrated for installation in older vehicles. That means many of the features required for late-model production vehicles are "turned off", because they're not required in older cars and trucks. That means features that may trigger a diagnostic trouble code and possibly affect performance - requiring additional tuning - are not enabled.
These inclusive kits deliver all the components required to plug into the engine and get it running - from the controller itself and the accompanying wire harness to the mass airflow sensor, oxygen sensors and even a throttle pedal assembly for engines equipped with an electronic throttle body. The kits also include detailed instructions to help you do it right the first time, even if you have no experience.
Each Chevrolet Performance controller kit is a true stand-alone system. All that's needed to get a vehicle running with it are power and ground sources, a high-pressure fuel pump and an electric cooling fan.
The Chevrolet Performance T56 Super Magnum Six-Speed Manual Transmission is a high-torque capacity TREMEC six-speed manual. Specially designed for custom, retro-fit installations with Chevrolet Performance crate engines. The exterior case similar to fourth-generation F-body transmission with the stronger, high-capacity gear sets, input shaft and output shaft used in the TREMEC TR6060. It also features a 40-tooth reluctor ring that's necessary for use with electronic vehicle speed sensors used with Chevrolet Performance controllers.
Get your new T56 Magnum bolted to your new engine with this T56 Super Magnum installation kit. Kit includes all the correct components that Chevrolet Performance offers to easily mate your new engine and trans.
