Gear Ratio and RPM deciding on gears

I run 4.56's and a 27 inch tire.

Need to know more about the combo.

It's mostly about what you can live with, and the rest of the car.

Road use?

Track only?

Details matter. ;-)

well, all we have to go on so far is "70 mph". IF his car needs to travel 70 mph for distance, I'd go 3.23's max, my opinion
