Alright chummins or stick with chevy???

It's official, I'm pretty sure I sold the chevy 2500 so now I have no choice in the matter. The dodge is a 4x4 but I have a 2wd output shaft and tail housing for it. I plan on the C-10 getting good fuel mileage. I was thinking of a rear end ratio in the low 3's, Any sugestions on what to put in the rear? I want it to hold up from the torque but also cruising on the hwy at 75-80. It kind of sucks, the friend I bought the c10 off of recieved the truck from his dad before he died and the engine has never been started. What a shame.
