So running the EFI motor with a 727 you dont have to do any thing special to the computer if you not running the stock trans as lomf as you can power the ecu your good.
OBD1 EFI doesn't control the trans at all. Some dodge trucks and panel vans came with 727's in them in the early 90's. Thats where my 727 i was using came from, already had the bellhousin notched and everything.
