Had a great 1st pass, full pull, still need a lower ratio to get my rpm back to were I used to run with dot tires.. Does any one know how many rpm are gained by each point in ratio changed, Im at 23-1 now , thinking maybe 25-1,

4lo.com has a great gear ratio calculator.

from 23.25 to a 24.26 at 29mph it changes the RPMS from 6663 RPM to 6953 RPM

23.25 to a 24.94 at 29mph it changes to 7148rpms. so I'd say around a 425-500rpm jump

Thanks for the info guy's, found a set of 2.55- 1 gears, should put me right at 71-7200
