Spark Plug recommendation; blown 360

I don't know what kind of heads you are running; Magnum or not... If they're not Magnum heads, they may have a different thread and might not fit; that was one concern.

Is your engine supercharged? I assume it is, but have no information about it. If it's anywhere near what I have, I'm sure they'd work for me, too.
Send me an email at [email protected] and I'll email you my address.

I don't have a PM account.

Thanks VERY MUCH for the info; I appreciate it a lot. I'm about to get this thing running with the blower for the first time, and I don't want to screw it up with the wrong plug.... I've waited a long time for this.

What is your motor setup, Bob?
