After yer post, I'm coming to believe that most of the noise is engine, and reasonably normal. I feel I've got some additional drivetrain noise, but with 166K I can't kick. The old gal is still ultra stable and fun. Next project is putting Redline in the driveline - It'll be interesting to see how things quiet down (and what comes out with the change...)
