Oh yeah, I get it! I have 3.91s and I wish I had 3.55's. If I drive at 65 I can damn near watch fuel gauge drop. I once had a 65 Belvedere with a 383 and 4 speed and it had a 4.10 sure grip so can certainly understand. I always wanted a Gear Venders overdrive but unless I hit the lottery or rob a bank it's out of the question. By the way, I just remembered that this is a Truck Site! This pre-senility sure is fun!
