I've always had a real bad high speed vibration and noise, so I did a few things to remedy this while the trans and TC were down. I added a CV joint to the rear drive shaft, and had it balanced. I also had a bad rear pinion to drive shaft angle, so I had new main leaf springs made and re-arched the entire pack. Then I had to figure out what height of block I needed and what angle I needed it at. Then there were a number of incidentals that needed attention. Anyway, today was the day that I started it back up, and went for a drive. She ran GREAT! I appreciate everyone's insight and knowledge sharing.
