I am new at this, but went ahead and bought a "frankenstein" '51 3100. It has a 350 ci engine, but don't know the year. Don't know the tranny (could be orginal), or the rear end, but told the rear end has been replaced.

I tried to replace the brakes, but could not find parts since I did not know what I was looking for. Easier to start from scratch.

So, my question is, do any of you all have recommendations for what I should put on as a replacement? Looking for gas mileage/highway speeds over burning rubber, so I am thinking 3.73 or 3.55 ratios.
