This run shifted at 7,400 and it fell back to 5,700 rpm.


That's what I figured.... Loosen that thing up a ton.

What size converter is it? Bet its a 9 inch. I have the tightest 8 inch anyone can build in my car. 2870lbs 1.18 60 ft. 850 or so HP. Flashes 6300. The next is a loose 9 inch and I don't have enough HP to make that work.
