Changed plugs to Autolite 3926 and also narrowed gap a bit to ~37 thousandths .
Have heard lotsa storys about Champions plugs being for RAM brand and , Autolite being the choice for Ford vehicles.

I use NGK's

1. Are you running nitrous?

2. You got an aftermarket ignition?

I would think that your current gap (.0037") would be a bit too narrow except if you have forced induction. Opening it up a bit may give you a better spark. Stock is .0054" I suggest between .0045" and .0050" with aftermarket heads and autolite 3924 plugs (2 steps cooler than 3926's)

Hmm have set em at .037 think not .0037, maybe my understanding of thousandths is off ? Seems to run a bit better. My engine has 10.2 compression . Check my garage , car data is in there.
Thanks for tryin
