Need to gain 3-5 mph. Right now 4th is 26-31 ratio of 22.2:1. I would like to keep this gear and mabey swap any of the others. Never been into this tranny, so i really dont know what i'm doing. Any ideas/suggestions appreciated. This is a 210 with D21 rearend and trans.

The only guy I know that messes with these transmissions is Mark Gettinger. He has lots of custom gear ratios made for him and in stock. Very knowledgeable guy. 765-977-8348 is his cell number, and he does text as well.
