No you're not right. An ignition system doesn't make power based on the capacitors. It makes power based on the fuel-air mixture in the combustion chamber.
You'd be smarter to index your plugs than spend time and money on an aftermarket ignition system for reasons already mentioned.
Your Mach 1 is not an "old hotrod." An "old hotrod" had an ignition system designed for low compression. When a high compression engine is installed you need a stronger ignition system to get a spark. So an "old hotrod" needed an upgraded ignition system over the stock one because THE ENGINE WASN'T STOCK. Hope that was clear
Spark plug gap is increased if you need a stronger spark (you know, higher than stock compression) and have an upgraded ignition system. The increased gap increases the voltage required for the spark to fire. If you have higher compression than stock and an aftermarket ingition system to accomodate the higher voltage, you have no reason to use the stock plug gap. You would then experiment with increased gap to find the smallest gap that works. You'd have to watch so the strap eletrode doesn't contact the piston, so you are limited somewhat as to max gap. On a stock ignition system this is a sure way to fry the ignition. You'd only do it on something that was entirely aftermarket and only because you had to.
And can we all agree that just because something was done on an old hotrod doesn't mean it should be done on a new factory car? At the very least understand why it was done before running off and duplicating it.
I hope you are getting the fact that these "old hotrod tricks" are coming from engine swaps, not getting more power out of a bone stock machine.
I wouldn't be surprised if the E3 plugs cost you power. That's just a retarded idea. And their graphs and "data" are so obviously fabricated it's entertaining.
You'd see a gain from a dyno tune on a stock car with no parts changed. I don't see why you'd throw money away on an aftermarket ignition and crappy plugs first, though.
