i currently run on a 1/2 mile but have found a couple tracks near by that will be running specials for pure stocks this year. they are 4/10 &3/8 miles what i was wondering is if anybody knows a formula to figure what kind of tire roll i should run? right now i am running a t350 in 2nd gear with a 3.08,8.5 in rear end i have been running 79-80in on the rears now but need to figure if i should go to 1st gear with taller or just go smaller and keep it in 2nd. my rules say any 7 in passenger tire so i'm open to any suggestions
