after reading "no spark" thread

[arkusvt]

I decided to refresh my ignition.Went to Rock Auto looking for a new coil. There are 7 choices listed for a '56 Mark ll. 4 of them are listed as 6-volt, 2 have no voltage noted and only one is identified as 12 volt. ??? There is no customer service by phone with them. I would like a quality American made part, would appreciate suggestions. Thank you

You should keep your posts on the subject in one thread. Get the 12-volt Pertronix II and bypass the coil resistor to give the unit full voltage.

Thanks on advice for subject; didn't get an opinion on coil, (see 7 choices, above). I see on some pics of nicely restore cars that they use the tan top standard Ford coil. I have used those coils with pertronix l conversions on both my '57 bird and '66 mustang with standard 7mm plug wires and have no problems. Question is would that coil and wires live ok with the pertronix ll? Thanks again, Barry.

It would work, but not as well. I don't think you'd get the advantage of the larger spark plug gap's physically longer and hotter spark. I can say that the hotter coil and wires accounts for a lot more gas being burned, rather than exiting the exhaust system as a bunch of fumes from unburned gas.
