Gear Ratio Selection

I want to make sure I will be happy with my gear selection. The car is getting 29-15.5-15 hoosier pro-street tires. 440 727 combo. I have a set of 3.89 gears from mosier and I want to know if this a good choice. I plan using the car around town and very little highway use. I don't really have any plans taking the car to the track. Maybe someday. Does anyone know what rpm I will be turning at 60 mph? Thanks for your input.
