I need some advise
Just installed a 68 block 426 hemi into my 72 cuda. Engine was totally rebuild from ground up and installed by a friend of mine. The engine was machined by a shop that went bankrupt while my engine was in the shop. It took almost a year to get it back and had to be put together by another shop. It starts first shot every time but vibrates like crazy at idel and when accelerated. I do not drive it for fear of damage. I have a feeling that the harmonic balancer ( vibration damper ) is incorrect. Any ideas? and how can I tell if the one on the car is the correct one in the first place. Any help would be much appreciated. The number on the balancer is 1604 2.
