47 V8 ignition mystery

[Don]

Didn’t one of the early post say he monitered the spark and was missing the spark on a couple cylinders,look like the problem would be in the distributor rather than the engine ?
I have a old sun machine I’ve spun dist up and seen it miss a few flashes,just like it would when on the vehicle,if I remember,the points spring were weak if using a inferior set or older set.I vote for a troubled distributor!!
