were looking to get a few more rpms out of the motor and keep it from dropping so far in the corners. and to help get a better pull on restarts. we currently turn around 6300 and would like to get up around the 7000 range. we currently run 5.42s but we have a set of 6.13s we could swap to. do you guys think this will be a big enough jump to get us into the range we are looking?

Rough idea is RPM / current gear X new gear = new RPM.
6300 / 5.42 = 1162.36 X 6.13 = 7125.27 RPM
This will vary as you will be changing speeds entering and exiting but it will give you an idea where you will be.
