GM Performance LS3 480 HP 376 6.2L V-8 Engine.
Our engineers took a production LS3 and swapped the stock camshaft for the racing inspired LS Hot Cam , which delivered a stunning 480 Horsepower and 475 lb ft torque. Thats nearly 12% 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 longer to draw in more air from the rectangular port L92 style heads.
The crate engine package includes the intake manifold, throttle body and fuel rail, along with the ignition system and exhaust manifolds.Installation Notes*Assembly does not include any electronics*Use LS376/480 Controller Kit P/N 19258267 for engineoperation, Kit includes electronic throttle pedal, which is required for throttle input tothe ECU*Includes Chevy SS wet sump oil pan*Intended for pre 1976 street vehicles or any off road vehicle*Not intended for marine applications
