More info on what you have for gear ratio, tire size and type of engine/ stock...  It all makes a difference as well as how you use it...

Are you wanting to know what needs to be changed to do the swap?
move the crossmember mount, potentially a new drive shaft, trans and converter... short answer.

IF your th350 has the 9" tail shaft you can just put a 700r4 in its place with no new drive shaft. if its the 6 or 12 you can do the math you will be plus of minus 3" and you will need a new shaft. but both trans use 27 spline output shafts so you can reuse the old yoke
