I am picking up the engine and trans this sunday. It will be interesting. I have learned a lot about cummins already. I have read a hand full of people have done this same basic swap. There trucks seem to handle the weight. I learned that I can put 2500 or 3500 2wd springs in it or I could just put a set of airbags in the springs to help hold it up. This should be a fun project. I will probly put a decent lift pump on it to start with and a mild tune and I am sure down the road it will get better injectors. Most likely the tranny isnt going to last long so I am sure that will be one of the first things needing upgrades.
