3.55 vs 3.91

I've run both and personally for a street car I really like 3.55's but if you are rarely going to go over 60 mph and do want to race it the 3.91's will work well for you. I ran 3.91's for years, used to drive my 340 Dart to the track (about a 60 mile trip one way) and had good luck with it. I have also run 4.56 gears on the street and well that's a tad much for highway driving LOL.
