stocker spark plugs
 

What spark plugs and what gap are y'all using in Stock? I am using Autolite race plugs now, but am always looking for a better alternative. Engine is a 307 Olds with a best of 11.81 this year.

I am also USAF retired as well as a retired teacher. I am also originally from PA. Grew up in the countryside around Shamokin, PA. Visit my parents there at lease once, mostly twice a year. How long have you been racing K/SA?

I have been racing Lattimores old Black car for over 10 years. Now I have a 350 chevy in it just because it is easier :) USAF Master Sgt retired.
