LS376/480 Connect and Cruise

The Chevrolet Performance Connect and Cruise is the quickest and easiest way to get your project hot rod or muscle car up and running. The Connect and Cruise kit have been designed and components carefully matched for optimal compatibility and performance, while also identifying the complementing engine and transmission controllers, and supporting installation kits.

LS3 with a Hot Cam

The engineers at GM Performance never stop tinkering. When the engineers took a production LS3 6.2L (376 cubic inches) engine and swapped the stock camshaft for the racing-inspired LS Hot Cam, the result was a stunning 495 horsepower and 473 lb-ft of torque.

Chevrolet Performance wasted no time in adding that terrific combination – dubbed LS376/480 – to their 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 a little longer to draw in more air from the rectangular-port L92-style heads.
