Had it up on stands today and while going over the car nutting and bolting it and looking it over I had a pretty good "aha". The drivers side motor mount has two bolts in the block side. One was missing and the other was loose! I thought OK good find take my public humiliation at leaving critical fasteners loose and get on with it. While replacing one and tightening them both I clearly remebered doing them up. You guys know what I mean as they are a trick to get to, esp the drivers side. Anyway got it back down to test and it does the same thing at the same RPM. Not as badly now it's tightened down again but definetely there very noticeable and consistent. I've come to the conclusion I'm commited to going in as the vibration is so bad it's shaking fasteners loose. Thanks for your ideas, I'll check back on your suggestions and keep you posted.
