Ok, so I just got my 66 Dart GT back, I had a 360 engine and an 8 3/4 rear end installed. When you drive the car, especially at 20-40 mph, it vibrates like crazy!!.. as you increase speed the vibration decreases but it is still there, not quite as intense. The tires and wheels were just balanced, the driveshaft was cut and balanced, The motor was dyno tuned, I am at a loss. any ideas??? thanks, John
vibrates like in the body or in the susenchen?can you feel it in the sterring?in the break pedel?or both?if its both it is out of balance.sterring.could be bushings.pedal could be a combo.need more info
