Chevrolet Performance 19435100 LS3 6.2L 376 C.I.D 495 HP Engine

The LS3 delivers a stunning 495 horsepower and 473 lb.-ft. of torque. That’s nearly 14 percent more power and torque. 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.
