The hot cam adds heat to the LS3
 
Our engineers never stop tinkering. When they took a production LS3 6.2L (376 cubic inches) engine and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), the result was a stunning 495 horsepower and 473 lb-ft of torque.

We wasted no time in adding that terrific combination – dubbed LS376/480 – to our 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.

Use the LS376/480 with a controller kit (P/N 1925267), which includes a special pedal for use with the engine’s electronically controlled throttle.
