Champion J11Y/Mopar P-34P spark plugs

All thats fine if it trips your triger. The hobby goes to the extreme in both directions.
That's why it is a hobby we all have different tastes........but we should come together and enjoy all builds......

'tis what it's run since the engine was rebuilt in '79. No point trying something different now! :)
Falls in line with what most have chimed in on.....if not going correct...use what you have proven to be the best choice for your build....

The "Mopar" branded plugs back in the day were almost "freebies" in the great parts hunt days....it is amazing they are around 20 bucks today, lol....

Actually, dare you to find more for that.
All of them I've found so far are quite a bit more. :)
 
So...…
do I use these or hoard them?
:rofl:

It's not everyday one runs across something like those still in their packaging. Personally I'd save them as they are. Of course I get a kick out of saving certain old automotive parts, old cans of oil, etc.

simple search on flee bay.....lol....but will the shipping cost deter you? So whats 7 bucks, right?........Or is that "quite" a bit more, lol...

Man I am so glad I didn't let that set of real j11y's go for that.......:thankyou:
As it turns out, that's the same dude I got mine from!
Looks like he's got a stash of 'em. He's trying to get a bit more from this set.
Maybe I should begin hoarding with his stash. :)

They do make for good garage dsplay items.......

That's what I do with most of the incorrect NOS parts....looks cool
 
Sure are lots of info and opinions on spark plugs.I have been using NGKs for years and have heat ranges from 7 to 10 in my track tune box depending on the boost level.
What I have not read here is how you guys test to be certain your jetting and heat range are proper:popcorn2:

Oh man, here we go again.... :lol:
That wasn't even my original question, HI.
I'll also grab some popcorn on that one....

Asking again:
Do I install these or keep 'em on the shelf?
We have 2 or 3 saying "install", one saying hang onto them for posterity. :thumbsup:
