GM Performance Hot Cam adds Heat to the LS3
Chevrolet engineers took a production LS3 6.2L and swapped the stock camshaft for the racing-inspired GM LS Hot Cam, which delivered a stunning 495 horsepower and 473 lb.-ft. of torque. The key to the power boost is the Hot Cam's duration, which allows the valves to stay open longer to draw in more air from the high air flow rectangular-port L92-style heads.
