Def not done by man, the other 5 plugs look normal.

I wish I could remember which cylinders it was last time to see if it is a trend with the same cylinder, but I don't remember.

I mix race gas with pump gas because I was having issues with the fuel boiling when the weather would get hot ever since they started to put ethanol in fuel.

Ignition is an MSD 6AL box, running MSD street fire 8 mm plug wires.


Well, if they were "blown off", you would think you would see marks on the pistons / combustion chamber areas?? Did they all just roll out the exhaust without hitting anything? I guess that's possible? From the slant of the electrodes, looks like they were firing, even with those gigantic gaps - and the edges of the ground straps are still very crisp. Something is missing ( info ) from somewhere.
