1972 Dart Magnum swap, R46RE Trans

My plan is to keep the EFI and run the Doner PCM (1999 Dakota R/T)
On my list is to find someone that can remove some of the things that will not be used, ie Evaporative, Catalyst monitoring, ect..
Thats the idea. I know going Carb and there is something available for the trans, would be the easy way.. But, I only know the most difficult way ...
