I wish I had a /6 head setting some where and see just how much room the NGK took up in the cylinder compared to the other plug
The ECU and new hotter coil along with the plugs I am sure helped the outcome. But I was thinking about taking up more room it might have raised my compression just a bit.
I guess I was thinking to much about it tonight after another cruise I took today. Silly of me to think that I guess 1970Duster.
