electronic ignition was "Re: IML: Spark plugs for a 68 - 440"

In my "lesser" Mopar I have a similar setup to yours but skipped the ECU, just the newer EI voltage regulator.  Running Autolite 85s with no problem.

 

If you have low compression heads (9.5 or lower) or a cam with a lot of overlap you can extend your gap to .050 with that setup.  With high compression heads and little overlap, leave it at .035.

 

Happy motoring,

I was following this thread and wondering how the ignition effects the best type of spark plug.

I replaced my stock ignition last year with a new Mopar distributor with "low performance" vacuum advance and an Orange ECU and an MSD Blaster II coil which I believe puts out 45,000 volts.

Has anyone done this and do different plugs work better?

I have used Autolite 85s with excellent results.  Considering that the newer and more expensive spark plugs are intended for cars with newer and more expensive electrical systems, I do not see the value.  Our plugs get removed/inspected/replaced far more often than those in newer cars.

Sneak preview the all-new Yahoo.com. It's not radically different. Just radically better.
