Well, depending on what year or years you are talking about, the transfer case should bolt up to the transmissions extension housing. Although I am not sure I would do that as I am 99% sure that a transfer case from a small block application is considerably less durable than one from a big block application unless you have a case from a 3/4 ton pickup that was powered by a small block. But either way as long as you are only trying to interchange the transfer case it should work. If you are trying to interchange the transmission and transfer case as a unit then no it will not work as the big block has a larger bell housing pattern then does a small block on Ford applications.
There are adapters for everything.

No the 350 small block will not bolt up to the 3.1L V6. The 3.1 is a 60 degree block V6 and the 350 is a 90 degree block.
