This wouldn't be from a dyno sheet..Just experience.
It will go faster if you get it out of first gear sooner.

It goes slower shifting lower.

This thing is such a dog in high gear you almost have to hold every gear as long as you can, if you shift 3-4 200rpm lower it will barely climb any rpm at all, just sits at 6800 and lumbers to the stripe. I don't know if it's the 1 goofy head thats on it or the cam. Hopefully we get some real dyno time at the end of the year to swap some parts and figure it out.

Something sounds off.........it should be making maximum power right around 6800 rpm.What rpm does it drop to on shifts.

5800-6000 Also Glenn in my previous post I meant to say drops to 5800 and won't move.

Absolutely not. Just dead, no power.
