Coil Voltage question.
-
Hello, new here. Hopefully someone here can answer my question, as I wasn't sure where else to ask. I have a Chrysler 440 V8 that's going to have some parts upgraded/replaced soon, and I was wondering about Distributor Coil voltages. Is it OK to use a new coil with a higher voltage than the original? And what will the effects be of this change?
Thank you. -
You haven't said what year your car is. Does it have points? Electronic Ignition?
If you put to much voltage to a points ignition it will burn the points out sooner.
If it's elctronic ignition, the standard voltage will be fine. I am assuming that you are thinking of a high out put coil.
Sorry for any confusion but I may be a little confused myself.

My apologies. It's a 1970 Chrysler New Yorker 7.2L V8 Engine with the original Points distributor (not the original points obviously but the distributor itself is the same as OEM). I'm planning the conversion to an electronic distributor and that's why I was asking.
As opposed to using the original, I figured that a higher voltage coil would provide more spark energy and a more thoroughly burned mixture. Am I correct in this assumption? And would this be a safe thing to do? -
I have to be honest with you, if you are switching to an electronic ignition, I do not see the advantage of spending more money for a high output coil. I believe that most electronic ignition coils will produce something like 50,000 volts. That should be enough electricity to start the fire in the combustion chamber. There are many deciding factors to achieve complete combustion, not just a hotter spark.
I agree that the change to electronic is far better then keeping the points system when it comes to a more positive burn. I still have the original point distributor in my Olds and have no problems with it. Electronic ignition systems came about to enhance a better combustion therefore a cleaner emitting of exhaust.
This is only my thought process.

Here's my thoughts, keep it as original as possible while improving it's operation. Why scrap the original distributor if there is nothing wrong with it?? Leave the distributor and the coil alone and instead install a Pertronix electronic conversion to get rid of the points and there associated problems.
Thats what i did on both my 67 Pontiac 400 and my 69 Ford 428 cars, if you are careful and a little bit sneaky you can do it and it will take somebody REALLY looking close to see the upgrade. The improvement in starting and running is terrific. Just some of my opionion.
Thanks, Phil. -
You cannot go wrong with the Mopar electronic conversion. Mother Mopar pioneered the electronic ignition system and the rest have just been running the copy machine.
