Fluid Dampener How To.........???

Doc,

Let us know what you find out with your vibration issues. I have the exact same issues with only a few thousand miles on rebuild. I bought the car a year and half ago have only put 1,000 miles on and it has had the same vibration since I've owned it. I haven't been able to contact the owner who did the rebuild. I have a 70 340 coupled to a A-833. I have checked the fly wheel and harmonic balancer and they seem to be correct with no wieghts. I haven't been able to verify if the crank is indeed a steel crank it left the factory with. I'm going to take it to a local engine builder to look at hopefully this week if the weather cooperates.
