Hei vs points.

I recall a youtube which does more exacting tests, of points, HEI 4-pin, and GM LS coils, I recall. He videos in the dark and such. The LS coil sparks hardest. The advantage is you aren't sharing a coil between cylinders, which definitely helps at high rpm so more time to charge-up the coil. As shown, it is easy to jump a spark in the air (inches), and even easier in a vacuum (yards), and not so easy at high cylinder pressures, which is worst at WOT with a turbocharger. I doubt that with points you could set your spark gap at 60 mil, like in a modern engine, without misfiring when trying to accelerate on an on-ramp.
