A-833 2.47 1st gear change to 3.09

@go-fish, I've been down the same logic path you are on. If you haven't played with this calculator yet, you might want to do so.

Speed/Tire/RPM calculator

I've fiddled with it a lot to see what balance I can get for good street manners, decent acceleration and gear splits, and some kind of cruising mileage. As info, if you want to put in a gear or rear end ratio that's not listed, you can enter whatever you like into that field and the calculator still works.
