what ever you do DO NOT put that 200 4r in it!. the vibration problem with the ultra-torgue kit is due to the adapter shaft. there have been issues with the bolt patterns not being centered when they were machined. already been down this road. it's a good kit and if you know how to set it up, it's great. the people i have talked to that did the th 400 conversion said it's no where near as good of a kit.

so my advice is: either build the t/u, or do the ultra-torque conversion. use a 91-93 dodge truck trans. that way you get the overdrive and the only added modification is a vac. swith to activate the o/d.

But have a Great, OLD (i.e. experienced) tranny shop set it up!
