Is the firing order correct? Is the timing correct? Is the ballasted voltage supply to reisitant to current flow. Spark plugs?

By chance you did not drop a plug prior to installing it did you? I had the same problem with my 350 and it was due to a hair line crack in the plug insulator? Worth a try.
