So some food for thought for points users

A while back I was having hassles setting a consistent gap on my 383, so I measured every gap for a full rotation, there was a .004 spread and it was very random from lobe to lobe. It was a 50+ yo distributor so no real surprises there, but I wonder how true they were from factory? I wonder how many old cars that were hard to tune were from this? The mind boggles

A pedantic person could go through and file/polish down the taller ones to ensure an even gap, I just set the gap off one of the ones in the middle of the variance - so only a +/- .002 difference at most, not ideal as such, but a much better result than if I had randomly set it off one of the + or - .002's

In retrospect a dial gauge would be the easiest way to check that - didnt have one back then lols
