Post performance question

Right now I'm running a 350 w/ TH350 and a Dana 60 w/373 gears in my 72 c20 w/leaf springs. I'm thinking of swapping out the rear with a newer 1-ton dually rear w/ 4.10 gears. What should I expect for changes in performance such as gas milage, torque, RPM on the highway, etc. Any info would be appriciated.
