My old school 340 upgrades and results.

Reluctor looks different than most I have seen. Maybe anot early model or a mopar ignition kit the distributor is a cable drive tach model. The electrical tape is my work. The wiring was a mess inside the car. I shortened and cleaned up a lot of wiring. I don't know the gap because I don't have my feeler gauges here. They at work in my tool box.
