Thanks guys! yeah, i've played with the calculator. I already knew i wasnt going to put in anything unless it was down in the 3's. I wont be hauling anything other then dirt bikes anyways. This ranch truck has retired from its heavy ranch hauling days and will get to live out life relaxing. If i were to go 3.54 in the Dana, i'd be turning approximately 2500 at 65. Not bad. But being a high school senior heading to college at the end of summer i'm on a budget haha. ring gear will run about 200, plus i need a different carrier because i have a 4.56 and up carrier, plus the instalation kit, and then the labor to have someone do it because i dont have the pullers etc. big bucks. Maybe i'll go to the local scrap yard and see if i can find any used dana 60's.
