Ron, if you were to get a simple Accel HEI set-up (100 bucks including new spark wires) you could avoid all that distributor troubleshooting and move on to simpler things. It made life alot easier for me on my '68 400. I've spent thousands on this car, and that was the smartest 100 bucks I've ever spent. I can send you the part numbers I bought, they are readily available in your town for sure.
