For sale- brand new- never run out of GMPP LS3 480 Hotcam version crate motor
Cam, LS7 3 bolt timing gear and upgraded timing chain, high volume oil pump, stock LS3 valve springs.
our power-mad engineers started with the production LS3 6.2L (376 cubic-in) engine—including its rectangular-port L92-style heads—and swapped the stock camshaft for the racing-inspired LS Hot Cam (P/N 88958733) and the result was nothing short of astonishing. With no other modifications, horsepower jumped from 430 to 480 and torque rose from 424 lb-ft to 475—that’s about 12 percent more power and torque from a simple camshaft change!
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. As a result, peak horsepower comes earlier than the stock LS3 and the torque curve remains flat higher on the rpm band.
$400 + shipping takes it all, cam alone costs this much!
