Build Thread My Never Ending 89 Notch Thread

So I am still chasing the vibration here . I have narrowed it down to an engine vibration .

Down shift crusing 3k rpm keep Rpms up and slow the car down vibration feels the same so that rules drive line out .

I shouldn't have been so quick to blame it on the TRANS even with that input shaft play . I was foolish and should've pulled the bell instead of just inspecting .

My next thoughts are the dowel pins are worn on the PP causing it to dance at high rpm but again the bolts should hold it in place . or the fly wheel bolts are slightly backed out . Or the motor is f u c k e d .

So I have about 2,5 weeks to get my ass In gear and pull the TRANS again and get it all sorted out before American muscle show in PA . again I feel it has to be some error on my part during the install as it didn't have this vibe until we tuned it . Ah the joys of trying to go fast !
