67 Lightning, wish I still had it, traded it in for tubing for the bi-plane, big mistake the bike was more fun.
Well I haven’t heard any logic that would sway me one way or the other so this is the deduction that I have drawn. If you jump over a puddle from the sidewalk to the street or from the street to the sidewalk it’s the same distance, requires the same amount of energy. If the spark jumps from the electrode to the shell of vise versa it’s the same distance, the same heat is produced. I can’t see where that would make any difference in the ignition of the fuel as the arc is traveling at a speed that is so much faster than the flame front that its of no consequence. Light bulbs light and fans turn and spark jumps the gap equality well no matter what the polarity is.
There are libraries full of books that discus Conventional Current vs Electron Flow. In the end this debate equates to the “chicken or the egg”, “is the glass half full or half empty”, etc. Hole flow in sold state theory is a “hole” different subject. Again when you are talking about a spark gap it makes absolutely no difference in my opinion.
The only thing that makes any sense what so ever in my opinion is that GM wanted to make sure that you had to buy polarity sensitive components for your GMC, from a GMC outlet and the same for the Chevrolet parts.
