I have a 30 Tudor that I just got back together. It's my first Model A. I am working to get the bugs out, including a pretty good oil leak. The engine was rebuilt before I got the car. It runs very well, and can go down the road well at 50 MPH, with more to spare. The only problem is the vibration. While I would not call it severe, it is constant. At some ranges it pretty minor, 30 and 50 MPH. Many people tell me it is normal for a Model A, but I would like to make one better. I do have another engine, and would like to rebuild one myself and try to balance the parts myself. I mean the ones I can. Is there some info where I can get ideas on how to do this? I was thinking of buying a balanced crank, and then try to balance pistons, rods etc. Whatever I would need to send out I would, such as bearings. Any help would be great! Thanks
