Hey I have a 1985 GMC 305/700r/208np and currently is geared to 3.08 , I have GM 10 bolts, but ive been told thats pretty much the same axle as the Danna 44? idk. Anyways I have a 4 inch lift and 33s right now, and the power is pretty good, tops out at 90 or so but this truck is my daily driver so keep that in mind. I'd like to put 35s on it and was curious on what i should regear it to, 1. for power spinning those tires, 2. MPG if any of yall could point me in the right direction... Thank you!
