/6-225 to 318 Scamp conversion

It's highly unlikely that you would have a 727 in your slant 6 Scamp. Regardless, it's not going to work behind your 318 Magnum anyway. Get the trans that's in the 97 Ram along with the engine. There should be a thread here somewhere about getting the electronics working in an earlier car. The EFI system for the street is a way better system than a carb, but, if you want to revert back to one, you mainly need an intake, carb, air cleaner, electric fuel pump, and maybe a V8 throttle cable, brackets, etc. I haven't personally done the Magnum swap, so, others will probably chime in here for more details on mounts, exhaust, oil pan, etc, that you're going to need.
