Are you running a Tremec TKO-500, TKO-600, or T-56?

T-56 in the blue car (magnum'ized). Only use 5 gears local, but I've done three Goodguys road tours and have used the snot outa sixth, 540 hp, 3:73's, and in sixth at 80, 23 mpg....but didn't tunnel (2nd gen f body) and may need too...I think I'm at 5* down now and need to come up?
