Excellent gains on Kevin's all ready powerfull Magnum! Quite a build you got going there. When you installed the headers did you do some dyno tuning to dial in optimum air/fuel for the new headers and high flows to get max performance?
Very impressive! Right from the get go when you started this build...this cars picked up some wicked numbers, and you haven't even cracked open the engine yet!
You put a cam and some PnP heads with some big valves you'll easily be putting down 500 hp! = you goal right?
