I ran the RJ12YC plug but kept getting alittle ping once in while with engine tuned as best as I could get it for overall driving. I talked to my engine builder and he recommended a non-projected plug tip. I changed over to NGK BR6S, stock #3522, and the .060 over 440 likes them better. No more ping at all with no other adjustments.

Hmmm, I thinkk I should be alright then, since the 383 is smaller

NGK XR5 is what I run in my 400.

318 mopars don't like Champions mine kept fouling plugs and I figured it was time for a rebuild. I switched to Autolite #66 and haven't had anymore problems. We ran a set of Bosch platinum tips in one of our Neons and kept getting multilpe cylinder misfire codes switching to the Autolite plugs cured that too. The only time I had a problem with them is when I put a set of #63s in a 1968 Plymouth 318. After a year it wouldn't start because the plugs were fouled. Too Cold heat range.
