Ok first I want to say I searched and I could not find what I was looking for. I would like to put new spark plugs in my barracuda. I pulled one out to see what was in it, and it has champion rj9yc plugs (the 5/8 hex head) in it. It is a 360 with J heads, comp 268 cam, holley 750 carb, air gap intake and headers. I would like to go with autolites or even NGK's, and I am wondering what the right part number would be as I can't seem to cross reference it. I am also using MSD 6AL box with the pro-billet mechanical advance, and blaster 2 coil. Is it true I should run a larger gap than .35 ? and if so what gap should I run? thanks for any info.
