I wish it ran 11s But the new one just mit be there.
But anyway I have ran autolites and Champions. Due to my pop pistions and as Tight clearances that everything is I couldn't just off the shelf Plugs(meaning stock Plugs) But Mine always Ran Best On autolites.
And Not knowing Your complete Build. I would start with the stock Plugs(heat range) Check The plugs (read them/looks) change temp no more then 2 degrees at a time. Some have ran colder(or warmer) plugs In the center(3,4) 2,5---1,6 at different heat range. Not ever motor acts the same. So what may work for lets say John, Sally would'nt work for Bill, Jane. Got my point??
So i hope this helps }[oooooo]
God doesn't like ugly.
