Default Spark plug used in your 302
Hello,

I have eddlebrock performer heads and I am trying to determine the correct spark plug. The one currently installed is an Autolite 3927. I do not think it is the correct one since it shows to be for every foreign car out there. I was curious what spark plugs you guys use.

That's the same configuration plug as the AFR heads use and they recommend 3922 as a starting point.
3927 is the hottest plug in that group.

3927 hot
3926
3924
3923
3922 cold
3911 non resistor
3910 non resistor

Thanks Racer X, I guess it is the correct plug. I am no expert as you can tell by my question.
