What gear should I run at a 1/3 mile track. I run a 620 now on a 3/8 and push about 6000 rpm's.

Dean, I would run the same gear or jump up to a 6.33 or 6.50. A 1/3 mile track is smaller than a 3/8 mile. What track are you looking for, Mid-Michigan?

650 should put you around 65-6700 thats where you want to be

I agree with 17j a 650 is a good all around gear Ive ran them on small 1/4s all the way up to big 3/8s Itll be hard to go wrong with 650s....Towman

Depends on tire size and how hard you wanna crank it. I run 6.70 to 7.35 on a 1/3 mile, 6.50 to 6.86 on a 3/8. I usually turn 6800-7200 r's.
