How high to rev the motor

MODs are in the sig and on top of MS4 I have the PRC springs that are good to 660 lift.

I was doing 7K last year on a totally stock bottom end. Think I'm going to bump it down to 6800 to be a tad safer. It makes great power all the way up there but with stock heads you might be more limited up top.

I rev my 220/220 out to 6800 for best performance. Your cam would be a 7000rpm sitter for sure.

Best way is to dyno it and go by the hp/tq curve.

I wouldn't push the factory bottom end past 6500 or so, but that's just me.

Best way to tell is look at your dyno graph and see what RPMs it is at when it quits making power...I have a cam similar to the MS4 and I made power to just over 6800, I set my shift light at 6500 so by the time I actually shift the car would be right at its limit of 6800...
