what size gears to use

I have a 65 mustang, stroked to 408, 2800 stall, and what size rear gears should I use if i want to drive it on the street, say up to 50 miles. It's a 9 inch posi. Will drive it maybe once a week take it out a couple of miles and take it back home. Would like to take it to the strip at least once to see how fast it is.

Thanks

What size rear tires will you be running, and what RPM do you want to finish the pass at??? Let me know and I will punch it in to the calculator.
