Anyone drag race with higher gears in the rear end?

I run a 5:13 gear in my 72 Duster. Rear tires are 29 x 12.5 x 15. It winds quick but the taller tire helped alot. I was running 4:30's previously and that was probobly the way to go. Definately throw a taller tire on your car, fit the biggest one you can in there and test it out.
