Re: Spark plugs
I used Champions for a long time with out problems, until 2005 when I noticed the new set I put on my just-rebuilt 292 were sucking badly. Turns out they were being made in Mexico. So I switched to AC Delco. No problems. I think I used RN17YC on V8s. AC # is R44TS. My L6 292 uses AC R44XLS.
I heard somewhere the shorter Accel Header plugs burn out early, but I haven't tried them myself.
