Gary, I recently posted this over on another board. Before things became standardized at Negative ground in the auto industry some like Ford and Chrysler I believe ran at Positive grund while GM was negative. Some of the reasons Ive read of or heard over the years were:

Positive ground caused less galvanic corrosion where metallic frame members were joined.

Points lasted longer and less pitting at Positive ground.

Its easier to emit electrons from a hotter (plugs electrode) to a relatively cooler (plugs ground strap) surface, Similar to in a vacuum tube where a heater warms up the cathode which emits electrons to the cooler plate.

And finally another Gentleman posted he heard there was less Radio Frequency Interference (RFI) if the frame was at Positive ground.

No warranty on none of this I never actually researched it just recall articles etc over the years which I, unfortunately, didnt save.
