If you wanted to you could just place a brick onto the throttle and let it hit the governor and run it there all day long with no problems.

If I am unloaded I'll run my truck at 80mph all day long and not even give it a second thought. Loaded I'll keep it around 70.

With your 35's have you re-calibrated your speedometer for them?

As for swapping gears if I would do it I'd go to 3:55's. 3:73 is so close to 4:10 that I doubt that you would notice much difference. Also where you tow or haul things could help in your decision. I do most of my driving in Colorado with trips to Utah, Arizona, Wyoming and Idaho so I get into a lot of hills.
