The cam really pulls hardest at 5K+ and keeps on pulling even though it is cut off @ 6K. I wonder how much power I could pick up with a 6300 shift point. Or will the heads even flow enough to make power @ those RPMs?

I've read some people revving to 7100 with a stock bottom end. Someone was revving to 7500, but I don't remember if they had rod bolts or not.

I just know that if for the cost of shipping I can see maybe another 10 or so horses from more room to spin, I just don't want to gain a lil extra power but give up a motor.
