How to calculate gearing change?

[Jet Ski Puller]

Anyone know what the RPM increase would be for a given vehicle speed when changing from 3:73 gearing to 4:11 gearing on a '94?

Anyone tried this and had a bad experience?

DRE did it, I want to do it, Good luck and consider swapping an axle from a 95 and up with 4.10 and disc brakes in the rear, thats my plan
