I have a 1946 Chevrolet on a s10 frame. New fly wheel/new balanced drive shaft. Separated torque converter. Still have bad vibration in truck. Even in park.

If it does it in park then it may be the torque converter is the problem you can check a balancer by marking it at #1 then start the car give it a quick rev then bring it back to #1 if the mark has moved the balancer rubber may have broken. Or it could be the flywheel/flexplate is the wrong one.

Also check for misfire or wrong firing order and engine/transmission mounts as well.
