More about Connect & Cruise Crate Powertrain Systems

The Complete Performance Package!

When it comes to factory-engineered performance and convenience, nothing beats Chevrolet Performance’s industry-exclusive Connect & Cruise powertain systems. With one package you get the engine, automatic or manual transmission, electronic controllers and al the necessary wire harnesses. Even better, we deliver it for less than the cost of buying the components separately.

Our engineers matched the engines and transmissions for optimal performance and durability, so you can wring out every horsepower with total confidence! The specially calibrated controllers are designed for retrofit installations in older vehicles, for easier and quicker installation – and more importantly – operation without the need for third-party tuning.

The Connect & Cruise lineup even includes several emissions-compliant E-ROD systems in both automatic and manual.

We did the work to design and calibrate perfectly matched powertrain systems and covered them with a 24-month / 50,000-mile limited waranty.

Chevrolet Performance pioneered the performance crate engine, so when it comes to performance innovations that save time, money and guesswork, we once again lead the way! All you have to do is install, connect, and start cruising!

NOTE: All components, engine, transmission, torque converter and controllers are ordered and delivered separately.

Installation Notes:

  • Engines shipped with high-pressure direct-injection fuel pump installed
  • Intended for pre-1976 street vehicles, or any off-road vehicle
  • Not intended for marine applications

Chevrolet Performance engineers wasted no time digging into the new LT engine to find more power and they delivered!

The LT376/535 builds on the technologies and capabilities of the Gen. V LT1 6.2L and extends them with CNC-ported heads and the high-lift LT1 Hot Cam to deliver 535 naturally aspirated horsepower. It also employs the production direct injection fuel system, which enables more precise fuel delivery that supports a high 11.5:1 compression ratio which translates into big power.

The LT376 engine assembly comes with a production intake manifold, throttle body assembly, ignition coils, water pump, balancer and more. The LT376/535 loves to rev and achieves that 535hp in exhilarating fashion. Give your project this high-tech heart transplant and drop the hammer!

Backed by the T56 Super Magnum six-speed manual transmission for the 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 exterior case is similar in style to the T56 for a 4th-gen. F-body with stronger, high-capacity gear sets, input shaft and output shaft used in the Tremec TR6060.
