I was wondering what your shaft looks like. I went through the same thing, but even if I put in a new bushing my shaft had over .015 wear where the bushing was riding. So as you would rev the engine the dwell would change. I called a few rebuilders and was advised shafts in good condition were hard to come by. Most used cores were coming out of Mexico, but it was getting rare to find a shaft that was in good condition. I ended up buying a new aftermarket distributor. So, I guess I am saying mic your shaft for wear.
