Guess i worded that wrong. I was askin if it would change

The twin cam motor is done making hp/tq at roughly 5,500.That's not much rpm's.Each tooth is probably 200-300 rpms.
I just checked my dyno sheet and realized the tech didn't hit the rev limiter. My motor turns 6700 rpms . It was still on a pretty good climb when he let off the throttle at 6000. I probably need to visit a good tuner

Yeah i know redline is the danger zone but me and the rev limiter are real good friends, we see each other quite often. I just cant stay away! I talked to the guy who built my motor and he said it was built capable of turning 7500rpm but limited to 6700 for longevity. It is the quietest motor around. People hear it and cant believe it has 100+ hp until i blow them away.

The same primary chain will work, you will change the compenator sprocket and the clutch basket.
