Well, I finally got to spend some time on the car this weekend. I got the Edelbrock calibration kit out, and put the jets back to the stock size, drilled out the pump nozzles to .040, used metering rods to go one step rich, and bumped my timing 5 degrees, The stumble is 95% gone! I think with some more experimentation with the springs and maybe go to the .043 nozzles it will be completely gone. I am now very happy with the way the car runs, and thanks again to all who posted.
