Looking for suggestions on gearing (ratio & front driver size) for the Nashville Fairgrounds Speedway 5/8 mile asphalt oval with 16 degree banking in the turns. We're running Sr. Champ at 400 lbs. with a box stock project clone. The largest driver I found was a 23-tooth - just not sure if the BSP clone could get the RPM's up enough. Please help to advise - thanks in advance.
