    Looking for some advice concerning my runs. So I'm asking some questions and looking on the internet at some calculator comparisons, the car running the E.T.'s and MPH tells me with the combination of ring & pinion, tire height and trans that I should only be trapping about 5500 RPM's approximately. Well, I'm crossing at about 6600 RPM's give or take, I'm shifting from low into high at about 6800-7000. Does this sound like a loose converter to anyone else, give me some insight.

    Sounds like about the only thing it can be is converter too loose on the big end

    I was told that putting a bigger gear in it should help, anyone?

    I'd call the manufacturer and get the scoop from them. You don't want to guess on the convertor.

    I don't know how much a steeper gear would help on the big end I know it would tighten it up a little down low because it would put less load on the converter to get the car moving, call ptc they will point you in the right direction and are real nice guys
