I have a 69 351w also. I have the same vibration. Mines about 1800 rpm to 2300 rpm. I bought mine used. It was rebuilt with 3000 miles on it when I got it. I have no specs on the motor so it would be interesting to find out whats causing the vibration. I have an old duel point distributor that I thought might be causing the problem. Jim
