I believe that GM converters are roughly .700" wider thru the cross section front to back. So the shape may be different. That may be why there isn't a huge data base for very high power Mopar trans converters.
The convertor in the GTX is a 10" PTC that is as tight as they can make it and still have the turbo spool. The trans has every aftermarket part you can put in it. Next step is to space the trans back or use a Browell bellhousing and a GM convertor built for a 727. PTC will do it. On a side note the trans has a 2.10 straight cut gear set in it. Amazing how much power you can put in it off the line with this. If he was starting from scratch he would have a SFI case T400 in but too much invested in the 727.
