I got a 2007 GT some months back to go along with my 2003 Cobra. Car already had basic bolt ons including LT headers. I'm gonna install the FRPP Hot Rod cams in a month or so, while searching around I wanted to know how much these cams increase the engines redline? Most dyno graphs iv looked at with the FRPP cams show its making peak power a little after 6k rpms. Now I know im entering the danger zone pushing this motor past 6500rpms on the factory valve train and internals, what is the limiting factor to these 3v motor when spinning that high?
