450 HP... geez! I remember when they released the GTO with 350 stock HP, thinking to myslef... OMG that is awesome. Then the LS2 with 400 HP came and I was floored! I am now very glad i didn't go out and get one of those GTO... 450 HP is NUTS stock!
Throw a cam in there, CAI, new exhaust and headers, and a custom tune..... be pushing 500 HP!!!
