Re: Spark Plug Gap

I imagine 0.035 to 0.045 gaps would be a good starting area. If you're really worried over it gap a new one throw it in and run the car and then read it.

I run 0.035s on my 3910 AutoLites but there a pain to gap since it's a racing plug you basically have to pry a screwdriver in there to get it to move.
