Want to go from 3.42 to 3.90 because i am switching out the rear end for a 9 inch just want to know what gear ratio you think is the best with mods in sig. Could go 3.73 or 3.90 or 4.10. Any one who has done this please chime in and tell me if you think it is too much or too little.

My mods are similar to yours. Tqr V3, Patriot 243's, Fast 90/90, 3600 stall, etc. I have 3.90's and like them. If anything I would go with more gear so I could possibly run more tire, but for a 26" tall tire these are fine.

well, I went different than the norm for my 6 speed. I went with 4.30's in my 9" and absolutely love them. I would say go for it, and if you have to you can always run a taller tire for the track.
