Info

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.

GM 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.
