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 our 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, electronic control modules for both, 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. Better still, the systems' unique SuperMatic transmission controllers are designed to work with the engine controllers 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.

All you have to do is install them and start cruising!

LS376/480 Engine
The hot new small block V8 in the Chevrolet Performance lineup is the hyper-aggressive LS3. It offers a high-revving 376-inch combination that represents generations of small block V8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this potential, the engineers at Cherolet Performance Parts offer you the LS 376/480 - an LS3 with an upgraded camshaft that ups power by a whopping 50 horsepower!
The LS 376/480 comes with the same great features as the LS3 crate engine. The bottom end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port units that share their design with the amazing LS7. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft.
The GM Performance Parts engineers picked the LS Hot Cam (p/n 809-88958733) to take the LS3 to the next level. This cam specs out with .525-inch intake and exhaust valve lift. Duration (@ .050 inches) is 219° intake and 228° exhaust. This cam allows for a dramatic increase in power across the power band while still maintaining good street manners. The engine will idle and cruise just like an LS3, but the extra 50 horsepower increase is there whenever you need it!

    Engine Control Modules and Harnesses
    A precisely calibrated engine control module is essential to making your fuel-injected LS 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.

    Most Engine Control Modules Kits Include:
  • Two oxygen sensors
  • Two oxygen sensor mounting bosses (for installation in the exhaust system)
  • A mass airflow meter
  • A mass airflow meter mounting boss (for installation in the air intake system)
  • A throttle pedal assembly (for use with the electronically operated throttle)
  • A specific oil pressure sensor that is compatible with the harness (when needed)
  • A complete wiring harness with fuse box and necessary cam sensor and MAP sensor jumpers
  • The programmed controller
  • An instruction sheet

    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.
