you can get close. I chose to go with JWT heavy valve springs, JWT 400+ Cams and rose my rev limit to 7850. If you go with the Tomei Cams, Solid lifters, springs, and etc. Tomei claims you can have a 8500 rev limit with there springs and stuff.
The real question is why wouldn't you want to have such a high rev limit? Do you have a turbo that will continue to produce power at such high RPMS?
