I've ran 305's on 2 pickup's. Both are 7.3's with chip, exhaust, and intake. Both had 3.73 gears. One auto and one 6 speed. I didn't notice any seat of the pants difference, and no change in fuel milage. I say go for it.
well mathematically speaking, the taller tire will give you more rolling distance per rotation... ie lowering over all gear ratio. normal highway driving unloaded you should run a FEW Rpm's lower, but towning... you may be running a few RPM higher to have the feeling of the power.... but with 4.10's... you shouldnt notice any diffrence. i know my moms 150 with 3.55 and 285's you can feel the diffrence... picked up fuel millage unloaded.... lost it towing.
I know going from stockers to 35's,I noticed a differance but I have 3.73's as well.Not a huge difference but still a difference.Niothing like doing it on a gasser.
I went from 285 to 315 with 373 gears and an auto. Could not tell much difference. It was worth the change.
