For older style trucks, go with whatever your style or make preference, for newer trucks the superduty is one of the better ones as it already has a straight axle, has lots of room under the hood (even more than newer dodges believe it or not) for any cummins you prefer. I am looking at doing a dt360 ( 5.9 international) in an older body style truck sometime in the distant future. The dt360 is a bit heavier than the 6bt cummins and there are no conversion kits for them but I would like something a little different
