With Hot Cam
Chevy 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 HP and 473 lb-ft of torque. That’s nearly 12 percent more power and torque from a simple camshaft change!
GM 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 longer to draw in more air from the rectangular-port L92-style heads.
This Chevrolet Performance crate engine includes the intake manifold, throttle body and fuel rail, along with the ignition system and exhaust manifolds. Use it with the LS376/480 with controller kit P/N 19258267, which includes a special pedal for use with the engine’s electronically controlled throttle.
