Hi all, I have a '53 3100. It has a stock '56 235 in it with an open yoke SM420 and a 3.50 rear gear. It cruises very nice and I don't have any issues with highway driving. My math tells me that I'm turning about 2400-2600 rpm at typical highway speeds, and it definitely sounds like it. I would like to change to a 3.25 or maybe 3.00 final gear in order to drop the cruising rpm's a bit. If I change to one of these gears, will it become a problem with starting out or maintaining highway speed? There are no major hills where I live. Does anyone have experience with this situation? Thanks
