What I meant was that the coil in the MSD pickup produces a stronger trigger to the box vs a stocker. I suspect their pickup coil may have more turns which creates a stronger field for the reluctor to pass through. Sends a better "spike" if you will. You'd need an oscilloscope to see the difference for sure. You are correct that it has no effect on coil output, that's a whole different section of the ignition system. The energy sent out of the coil is only what's required to fire the specific plug that's being lit. The beauty of aftermarket controls with the mag trigger (or Hall Effect dist or crank trigger) is that instead of 12V through points (or more like 9) to the coil, my 7330 7AL3 sends 570V. Get some of the secondary side of that!
On a side note, I'm glad I bought a new 7330 last year at around $750. They are $960 right now!!
