Answer
Adam-

  While I admittedly don't know much about 4X4s, for something as big and heavy as a Bronco that's sporting 35" tires, I'd go with something in the 3.73-4.10 range...depending on what kind of differentials you're running.  A 400 should make decent torque and power to get the thing moving...the gears would just sort of be icing on the cake.  Hope this helps.
