Currently looking at doing a 12 valve swap on my 2wd dually and converting to 4wd. I will be converting everything over to 4wd first. Looking at purchasing a 1986 M1028 CUCV for Front and Rear ends and front suspension. With switching over to the GM Dana 60 in the front with the springs or may possibly put 6-8 inch lift in at this time what other steps are needed for the 12 valve conversion besides hump modification, mounts, and crossmember. It will also be converted to Single rear wheel.
