Ernest,
You might want to consider stainless rod. Good grades of stainless are not magnetic. They also are less likely to corrode. I used 1/4-28 SS rod (secured with aircraft grade nuts.) Not flying yet, but about 10 days from being ready for an engine start.

I spent the evening laying out my firewall forward. I was going to wait till everything aft of the firewall was complete, but I've got to get the general layout settled so that I know where the hoses and wires are going to pass through.
Anyway, I'm using the LS1 coils, and plan to mount them on the engine below the spark plug as several other have demonstrated...strung together with 1/4" all-thread and spaced with some 3/8" aluminum tube. But then I started to looking at what I'll be running that all-thread through, a bundle of thin metal plates that is supposed to keep the electrical energy concentrated within the coil. What will be the effect of running a steel rod through them? Will it connect them all electrically? Am I being goofy? Inquiring minds want to know.
I got my degree, but I never really ever got a handle on how those magnetic fields work. I can't even remember the proper names for all the parts.
