I have 2001 F250 Crew cab short bed automatic with a 7.3. I have been tossing the idea around of doing a 6.7L cummins swap. I'm thinking of keeping the 4R100 tranny in the truck now but im still throwing the idea around. I was looking for any pointers people have maybe your experiences, road bumps, maybe a recipe or parts list. I'm new to the swapping world and I'm not unbolting anything until I am completely comfortable. Thanks in advance.
