Jim is correct.
Especially want to hit the "hot coil" thing here. If your plugs fire at say 6K volts and you put a hotter coil on it they will still spark at 6K volts. When they advertise those things they are giving you what the coil will put at maximum resistance that the coil will overcome. Couple of different ways to increase the voltage to the plugs. As Jim pointed out a wider than stock gap is one way. The other way is to increase the pressure in the combustion chamber. The higher the compression is the higher the voltage has to be to make the spark jump the gap. The downside there is the higher the compression the higher the octane rating has to be to prevent ignition ping. So basically the "hot coil" is a rip off if you are running a stock engine. In a simple form what happens is when the points close the coil gets electricity. When they open the coil very quickly build voltage until it has enough voltage to jump the gap. But when that jump voltage is reached the coil discharges to create that spark. So it starts at low voltage and bulds until it can overcome resistance up to the max the coil can produce.
As far as electronic ignition is concerned I love it. Lets face it even what has been considered the better brands of points are getting cheaper. For years I've use Echlin, Standard and Blue Streak. The last set I bought was defective right out of the box. They are a pretty simple item to install too.

Today's Featured Article - Talk of the Town: Winterizing Engines - To Drain or Not to Drain? - by Russ Berry. What is this strange attraction I have to equipment and machinery? How did I get this way? I came from the suburbs and own a small horse farm in rural Loudoun County, Virginia. You can call me a "weekend farmer." The local farmers do. Does it bother me? No. I am just happy to have their friendship. At least the word "farmer" is in my title. But what is the attraction? How can I explain the sensation and exhilaration I feel when I turn the key and hear the engine come to life (most
