LS376/480 - 495 hp LS3 Crate Engine w/ Hot Cam

The Hot Cam Adds Some Heat To The LS3!

GM's engineers took a production LS3 and swapped out the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958753), which delivered a stunning 495 HP and 473 lb-ft of torque. That’s nearly 12 percent more power and torque from a simple camshaft change! Chevrolet Performance wasted no time in adding the new engine – dubbed LS376/480 – to the crate engine portfolio.

The key to the power is the Hot Cam’s 0.525-inch lift on both the intake and exhaust, along with 219-degree/228-degree duration specs. That’s a bit less lift on the intake side than the 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.
