A couple of things I would like to add based on a few years of working on engines.
Don’t skimp on the wire that connects the battery to the coil. The coil needs current to work well. When strands break off, it cuts the current down some. Think about how much water comes out of a fire hose than a garden hose.
Most all coils from way back require a dropping resister to reduce the voltage to them so they won’t burn out. I guess a hold over from the 6 volt days. Some of the high compression engines had a switch on the starter solenoid that would go around the resister when the starter was in use to give extra voltage only at start. Running a coil that way for very long will burn it out.
Electricity will follow the path of least resistance. If that is within the distributor cap, then that is where it will go if there is too much resistance through the plug wires, through the plugs and to the block (like loose rusty plugs).
I just love this part of an engine. My Deere has a mag but electricity is still electricity.
