circle c .. 5.9 will get ya better fuel mileage than the 6.7..6.7 has a little better power,, but both fuel system require strick maintance contaminated fuel or a clogged fuel filter is the biggest prouble with those trucks ..they use return fuel to cool the pumps so it's a must or you'll have pump and inj. failure.. the 6sp auto tran. used with the 6.7 is a good unit but with a 5.9 get the manual trans..  and 03-08 3500's are prone to ball joint and u joint failure but there farly easy repairs..DW
