what 4 speed auto transmissions can i use? 46rh etc

Hi all
I am installing a dodge 360 magnum 5.9l engine into my old 1972 coupe. I have looked at 4 speed transmissions and don't know which one to get. I have converted the magnum from efi to carby so I am not using a ecu. I don't think I can use the 46re as they need an ecu to change but I have used a 46rh before and it worked fine. I can get another 46rh transmission but I have read about some other ones A604 or A606 but don't know anything about them. Would these be any good for me? Or what other 4 speeds would be good for me to use?
Thanks Maca
PS I have found some rebuilt 46rh transmissions below for $1300 which sounds fair. comes with a new convertor too.
