LS3 Connect & Cruise with 6L80-E Transmission (3000 Stall)

If you’re looking for factory-engineered performance and convenience, nothing beats Chevrolet Performance’s Connect & Cruise powertrain systems! GM engineers took a production LS3 6.2L (376 cubic inches) and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), which delivered a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 14 percent more power and torque from a simple camshaft change! One package provides everything you need – the engine, automatic or manual transmission, electronic controllers and all the necessary wire harnesses. Better still, we offer it for less than the cost of buying the components separately.

No time was wasted in adding this terrific combination (dubbed LS376/480) to the crate engine portfolio. The key to the power boost is the Hot Cam’s 0.525-inch lift on both the intake and exhaust sides, along with 219-degree/228-degree duration specs. That’s less lift on the intake side than the stock LS3 cam, but considerably more duration, allowing the valves to stay open longer to draw in more air from the rectangular-port L92-style heads.

Engines and transmissions are matched for optimal performance and durability, so you can wring out every last ounce of 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.

Engine Specs:

  • LS376/480 (376 cu in)
  • 495 hp @ 6,200 rpm

Important Notes

The LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft complements the LS3’s tremendous airflow capability and enhances its broad torque curve. Out-of-the-crate horsepower is 430, with an impressive 425 lb.-ft. torque.

The LS3 crate engine comes complete from the SS-specific oil pan to the ignition system. It also includes the intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58x reluctor wheel and 14-inch automatic-transmission flexplate. The SS oil pan doesn’t suit all applications. Use the vehicle-specific oil pan for original LS-powered vehicles or Chevrolet Performance’s Muscle Car Oil Pan Kit P/N 19212593 for older vehicles.
