Re: Spark Plugs?

I did some research and decided to put autolite 306 spark plugs in to see if they give me any improvement. The 306 are a little hotter plugs. I gapped them at 28 thousandths instead of 25 because I'm running a 12v system with 65 Chevy coil. I'm pleased to report that there is a very noticeable improvement. Smoother idle and quicker response to the throttle.
