First, I am 69 (Brain starting to slow) and have never converted a 6 volt system to 12V. That means the part book components work. I have a 48 Dodge Power Wagon that uses an original generator and 6v system. The 52 Ford 8BA is being converted to 12 Volts with 5th Avenue 12V Alternator (Randy Rundle) and also Charlie NY SBC distributor. Rundle suggests a couple of 12Volt coils. What about the spark plugs. I have original cast iron heads. Not sure which plugs to use. Is there a difference between 6V and 12V plugs or does the coil used send out the proper firing voltage to the standard plug.
