Default Coil

The original coil in the Ford is only a 4.5 volt coil. The 6 volt supply is reduced via a resistor in behind the dash panel in most carriers. You would need to by pass this resistor if you fit a 6 volt coil.
The next thing is to change the condensor for one which suits the coil. (with a change of coil voltage it is nessassary to change the capacitence of the condensor, (measured in microfarads), other wise the contact sets (points) life expectancy will be reduced. The capacitance of the condensor dictates whether metal transfers from one contact to the other (or not)(please excuse the spelling) As long as the capacity is correct, the physical look of a condensor does not matter as long as it can be mounted and the wire can be hooked up. ... So ...basically you want a condensor made for a 6 volt system to go with your 6 volt coil. This applies to all standard coil ignition systems of this type.
Hope this helps.

Thanks Jordan and Lynn. To answer a couple of questions, the coil (right now) is on the dizzy. I want to use the adapter plate and a new 6 volt coil. The rad hose enters the head right in the middle at the top, not in the front as yours does Jordan. I agree about replacing the wires. I'm hoping that I can go to Princess Auto and buy the wire and ends. I haven't looked at the fuel pump yet. The glass bowl was filled with old gas which was like lacquer when I dumped it out. Next is the carb.

On a good note, the heads came off well and we've cleaned them up nicely. No cracks or dings and look really flat. We're building a crank to manually clean the valve seats as a few of them were really crudded up and likely that's why our compression was so poor.

Get your wires from Napa. Princess won't have them. I'd ask for the real wire type instead of the carbon ones but either will work. You will have to make them so buy the ends and the wire buy the foot.
