FBO's black HEI ignition box

RB,
Because you didn't find any power in plug gaps does not mean there isn't any. Power is not just at peak power, it is from idle on upwards.

No kidding? What makes you think I was looking at peak power ONLY? You assumed.

And I’m not the only one who has extensively tested plug gap and found ZERO.

But I have replaced a battery fired ignition with .035 plug gaps with a 4 amp mag that used an .022 gap and the mag was 45 HP up on that engine.

Most of the time it was a 20 HP gain over a battery fired ignition. All with .022 plug gaps.

Hmmmmmmmm…
