451 stroker rear gears question

I think the convertor is totally wrong or broken. New doesn't mean good, even from good suppliers. It's too loose. You should be trapping at 6200ish for 102mph so something's off. I don't know what John was thinking - you sure you/he heard him/you right? I'd get it back to PTC first to inspect it, second to lower the brake stall by 1800rpm and give it a flash around 3500.
