Engine miss

[Kahuna]

I convert them myself and a friend has the testing machine.
The coil is an original type that I bought some time ago from Macs. (now discontinued)
I use a Mopar ballast resistor,
I have this ignition on both of my cars and they run well. I use the Helmet type with the 11A advance on one and the 68 internals on the other.

Just as an added note, (you have to be old to recognize the name),
I also have a couple of coils rewound to 12 volts by the late and great George Pounden.
