Engine/drivetrain vibration?

Also, in re-reading other notes my guess would be that if there is an unbalanced situation with a cast crank/damper/tc combo you should be able to feel it without driving the car, because the tc is part of the rotating assembly... So, if you were in park and brought the rpms up you should feel the vibrations if it's out of balance... In my previous note, the weights have to be in the right placement, not just any weight anywhere... This is only advice, don't try this at home, we are not experts!... Hope your on the right trail....
