200-R4 transmission behind mopar stroker

I really like the GV unit, but I think there is a time and a place for that also. I've installed a few and have a friend running one, but am really concerned about the converter slipage in OD if you're running any sort of stall at all. It's never been explained to my satisfaction or comfort. Quote taken from Revhendo post.

I was running a 904 with a 9.5 dynamic 3500 stall behind a 575 hp 416 and had the GV unit. At 65 mph it would slip about 20% I figured and would heat the fluid up some. This virtually eliminated any help from the GV.
