MPH

I purchased my restored '29 coupe late last year so I am rather novice at this hobby.The max speed that I get out of it is around 45 mph (53 going downhill with a tail wind once).I just assumed that this is normal since times were slower and even Mike signs off with "God speed under 40".I just noticed in the "Model A Shop Manual" a chart that has RPM/Speed and my car more aligns with the AA truck. Now I'm not interested in driving more than 40mph (65 mph would scare me to death), I'm concerned that the RPM's for me to drive 40mph is higher than the average "A" driver out there. Thus premature engine wear.
I assume (oh... how I hate to do that) that this is in the rear end and not the engine.Is this possible that I have a different gear ratio than most cars?What should the ratio be?How difficult is it to modify the ratio to get the car more normal.
