I have a custom 65 F-100 build in progress so fitment and differentials are not big issues. I'm using a 572cui married to a 4R70W and was looking for some advice on a transfer case. Keeping in mind this is not an off-road build. Making 900+ hp and 860+ tq.

4406, 4407, 1356, np205

4407 or np205 might be the best choices based on your power goals

4407 was used behind the 5.4, 6.8, 7.3 and others in full size 3/4 ton and full one ton trucks
