74 Dart Vibration

As to what actually cured my motors vibration. Well it was a combination of things. First off the crank was out of balanced. The rods and pistons where not balanced. The line bore was off do to the #3 main cap not lining up right. Those are the things the machine shop addressed that he believed fixed the vibration. But thats just a small part of the many issues found with this motor. Over all this motor was poorly cleaned and assembled.
Glad to say now though it runs like a top and I'm very happy with the combo in this car. It's like a whole new car.
