or the question is, can i remove the engine (400) and put a 460 or 429 on the same trans...
Yes you can swap it out but you need to change the motor mounts that is all you need to do. Jeffs bronco graveyard has them for 130. The trans should be a C-6 and the t-case should be 203 or 205. I done this swap out all ready.
