LS376/480 Connect & Cruise with T56 Transmission

When it comes to factory-engineered performance and convenience, this LS376/480 Connect & Cruise crate engine is the complete performance package. Mixing the capable LS “Hot Cam” with the powerful LS3 6.2L takes affordable performance to a new level in this engine. With one package you get the engine, manual transmission, electronic controllers and all the necessary wire harnesses – all delivered for less than the cost of buying the components separately.  This LS engine offers 480 horsepower and 475 lb.-ft. of torque that will wake up your resto-mod muscle car, street rod or classic truck.

It’s all backed by the T56 Super Magnum six-speed manual transmission for thrill of selecting your own gears and a double overdrive to make highway cruising a pleasure. These transmissions are rated to 700 lb.-ft. of torque and are brand new from the ground up. They use an extensively modified transmission case to prevent leaks under high-stress conditions and increase overall power-handling capabilities. The engines and transmissions are matched for optimal performance and durability, so you can wring out every possible bit of horsepower with total confidence! The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation and for operation without the need for 3rd party tuning.

The exterior case is similar in style to the T56 for a fourth-generation F-body with stronger, high-capacity gear sets, input shaft and output shaft used in the Tremec TR6060. Kit includes shifter handle and Chevrolet Performance-logo ball-type shift knob to complete your install. Put this combo to work in your custom hot rod or muscle car and enjoy a great balance of performance and efficiency!

The Connect & Cruise lineup includes several emissions-compliant E-ROD systems available in both automatic and manual. Each system is designed and calibrated to perfectly match the engine powertrain systems and is covered by a 24-month / 50,000-mile limited warranty. Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, Chevy leads the way – all you have to do is install, connect, and start cruising.

Important Notes

For a complete installation, the builder will need to source additional components to complete the engine assembly and get the vehicle running, including:

  • Fuel tank and fuel lines (re-circulating or returnless)
  • Fuel pump – 58 psi (400 kPa) for all engines except LSA, which requires 65 psi (450 kPa)
  • Air induction system that incorporates the mass airflow sensor

Additionally, this engine requires a front-end accessory drive system. The instructions included with each kit lists recommendations and Chevrolet Performance offers several configurations to suit different applications. Each allows the installer to easily delete air conditioning. Note that exhaust manifolds are NOT INCLUDED.

We also recommend the LS1 Engine Installation Guide P/N 88959384, which illustrates basic procedures and offers helpful tips on installing an LS engine into older vehicles.
