When people say highway driving, 65 mph is quite a bit different that Interstate driving-75-85. 3.23's actually suck on the Interstate. Maybe most of you city slickers just putt around town all of the time. I grew up in a small town, Had to drive 15-20 miles just to get anywhere. I installed 4.10 gears in my 68 340 4 speed Dart one summer. When I pulled them out in the fall, I vowed never to use low gears in my cars again.
