Any Problem with Replacing DuraSpark II with Breaker Point Distributor?

I will spare you the saga (horror story) regarding the "why". Suffice it to say that I want to replace my DuraSpark II system with a '73 - '74-'74 AMC-type distributor which I believe was originally made by Delco.

Are there any problems of which I should be aware? And no, I don't want to try any other electronic ignition systems right now.

By the way, I am here because I didn't get very far with this line of inquiry at IFSJA.

Thanks.

Jeff

I"m sure you have your reasons which are valid to you and no, there is no problem with that idea. The points distributor will drop right in. I had a '76 Cherokee which a previous owner had replaced the electronic distributor (Prestocrap) with the Delco points distributor. I left it in there for quite a long time before pulling the engine for another project.

Just make sure the gears are matched

the points system also runs off the reduced voltage from the voltage wire. Prestolite takes 12v, points and duralast take 6v. Should be plug and play. I keep a points distributor all set and reasdy to install, just in case of that world-wide EMP blast

I think about what that would be like sometimes. All these new $40,000 paper weights strewn about the roads and old beaters being worth a fortune

and I would kinda like to hear this horror story. I could tell you about arguing with the guys at napa that "No, my truck has points. See!?!"

You will need a hot 12V line from the I post on the solenoid to the distributor.
You will need a 12V feed, run from the key through a ballast resistor to the distributor.
You will need to set the point gap (dwell)

Basic system

What you want. This is a GM system with the bypass coming from the solenoid (R) on the starter. Your Ford style system will have the solenoid on the fender.
