Electronic distributor and EFI
#1
Sorry if this has already been addressed but I didn’t find anything specific to my engine.

I have a 68 with a 318. Wanting to get rid of the points and update to electronic distributer. In the near future I also plan to update to EFI. Just trying to figure out what I need.
 
Anything specific I need to think about now that will be compatible when I switch to EFI?

I found the pertronix conversion to replace my points. I assume I need a coil but which one, there’s different Voltages?

Do I also need to replace the ignition box? Or anything else?

Thanks in advance!

When you run Pertronix, you can bypass the ballast resistor and run full 12V to the coil.

Before you purchase anything, I highly recommend contacting whatever EFI vendor you are going with and see what they recommend. Some will work with with points or a aftermarket points replacement setup, others will not. (Some system induce noise into the negative part of the coil and it interferes with the ECU). I myself went with a MSD all in one setup (ignition controller is built into distributor, alot like the older GM HEI setups were).

And one thing I cannot stress enough.. follow the instructions in the kit. If they say run a dedicated positive/negative lead from battery, then do it. Our older cars are very noisy when it comes to electrical stuff, and last thing a Efi unit hates, is electrical noise.
I love Mopars so much I'm date coding the skid marks in my underwear.
