I found some interference issues in the distributor cap that seemed to take care of a lot of the noise. There is still some metallic clicking at higher rpms but now I just don't know how sensitive I am being after hunting down noises for a while. The thing that threw me for the biggest loop was that my cast iron dist. made noise as well as the breakerless distributors. They use different caps so the cap interference couldn't explain the noise in both. It might be a case of my iron distributor weights failing at the same time as I was having cap issues with the other distributors. Coincidences can sure screw up problem solving.

thanks,
