There are a sea of spark plugs out there and I don't know the differences,I just want a good plug to run in my combo.There are platinum tipped,double platinum tipped,v-power,irridium,non-resistor,resistor,and Jegs carries the plugs without a j-strap,whatever that means! Someone please enlighten me!Thanks,John

Champions in the new Mopars and Autolites in the old.Ive never seen a Bosch plug run good in anything yet.Ive changed thousands at work because they are crap and cars run bad with them.If you got a car to run good with them go buy a lottery ticket.Rocky

This may not be any help but I have found the Champions to work well in stock small blocks and Autolites to work well in stock big blocks. Being a non-stock six-pack may require something different.

i use the rj12yc's in the 440, it runs fine. my 5/8" 440 plug is the bosch HR8BPX . i remove the tapper on a lathe.
the autolite 9323's, in the 318 with great results and a 5/8" plug.

um.. wrong. you can still get non-resistor champions all-day-long.

Yep Champions are junk, thats why they were the OE plug when these cars were new. I think your problem is running a resistor plug in that motor in the first place. Find a non-resistor plug in the heat range you want and try that. I run old NOS J11Y Champions and have never had a problem. But you pick any manufacture you want and find out for yourself which one you like because anytime somebody asks about spark plugs on here you get a different answer. Its about like asking which beer is the best.
the champions that were installed in the 60's/70's are a much better plug than the new champions , never had good luck running that rj12 in anything either .

Probably right John, but I still got 4 sets of the vintage NOS J11Y's left.
But I still have never seen anybody have any real luck running a resistor plug on a beefed up mill running alot squeeze and a hot ignition. Seems like whatever brand they run the stupid resistors burn out of them with quick.
