I have an 04 and my plans are to do the 6.1 cam. I’m already running the 6.1 intake and have a set off eagle heads to put on. I don’t want much more power than I have. I just enjoy driving it.
If you have the intake, hopefully you got the rails and injectors. They don't' "add" anything, but they'll prevent the 5.7 from "potentially" being starved. probably no big deal.
