Ok I have been thinking about this. It is going to be a long time before I can afford to get an AOD then pump the rear end up to 3.90's or 4.11's. So My question. Is it worth in the mean time to go to 3.50 over my 3.25'swill there be enough of a diffrance to even bother? I would also change the tranny speedo gear. We like to travel in the FBD so decent highway gearing is a must. Plus I like the quick get up and go. I have the 3speed C6. It would not cost much to do the said change and cost is a factor here.
