I think you're over thinking the whole deal. These are not rocket science and trying to make them rocket science is a waste. Just get a 6 volt coil from Chev's of the 40's or place that specializes in that sort of thing and bolt it up. You want enough spark to fire the plug, but especially on a babbitt engine, a massive spark, and other high performance add ons could result in premature engine wear.

It seems OK but not sure so I began looking for a better one. As I started looking I discovered that I can't find 6 volt coils but I can find 1.5 or 3.0 ohm coils. ?? So, I Googled everything I could and never got a clear understanding of which I needed so I measured the coil I got from the vendor and it is 1.5 ohm so I ordered a 40K Flame Thrower 1.5 ohm. On the box it says "suitable for 8 cylinder engines. Use 3.0 ohm coil for 6 or 4 cylinder engines except for racing." Can anyone sort this out for me? I am running 6 volts on a 216 6 cylinder engine.
