My friend Bill, who is a Ford guy and has owned several FE powered cars in his 68 years, has almost completed his build of a 300 Ford six with turbocharging and fuel injection. He's searching for info on a good spark plug to use. I've told him of the good help and information always available on this site (he's not a member of any forums) and he asked me to post this. Of course it's 18mm with the iron Ford head. Any turbo guys have suggestions I can relay to him?
Thanks.

The old Autolight 124 isn't a bad place to start. Might need to tighten the gap just a little.
A couple non resister options, NGK A6FS or colder yet with more tip projection AP7FS. Probably want to stay with a resistor option with the fuel injection system.
Can't get the AR6FS anymore.
I'm sure there will be more replies from people more knowledgeable than me on spark plugs.

Denso makes a copper u groove plug like accel i have had good luck with them rock auto has them at 1.34 each.

My iron headed 2.3 turbo runs the NGK version with a heat range of 7 on E85
Depending on fuel that might be a decent starting place
Feel free to ask if I can help I will

E85 can tolerate a hotter plug as well as ignition timing close to naturally aspirated. If this gentleman is not running E85, I would start with a #9 heat range and go from there.

Thanks everyone for your replies. I have forwarded the info to him.
