Those guys I'm talking about made a 2900 Lb. car run 6.17 at 234.+ MPH on a 10.5x33x16 tire with one of those trannies.
They had switch from a Mikes Monster Glide to the Proflyte when they were running a Ford motor in it with a lot of NOS, they later switch to twin torbos and them to crank driven Pro Charger on c16 and Q16. BobR was involved with that deal for a long time and he finally convince the car owner to switch to a Hemi up
I'm almost sure they don't use any stock parts in that tranny including the case, call them and find out scope

Mr.Cab Racing and winning with Mopars since 1964. (Old F--t, Huh)
