Howdy howdy guys and dolls!

1973 dodge dart custom, pepped up 360, largely stock ignition system, air gap intake, deep rock 650cfm 4brl carb.

Continuing on my revamp of my dart, I have heard it said a few times over the years that my choice of spark plug could be better.

In every mopar I’ve ever owned, I have run champion copper plus plugs. That’s just what dad and grandpa did, and it’s what I have done. However, since I am revamping with the “best components” during this redo, I wanted to ask the brain trust.

This will be for street juking and jiving play, maybe rare on the track, and driving around.

The rest of the ignition is largely stock aside from likely an upgraded coil and wires.

So, what do you guys recommend as far as coil, wires, and plugs?

Any help or insight or part numbers would be greatly appreciated.

(I’m not really interested in replacing with HEI at this point. Just improvement over what is there)
 
I've generally used NGK standard copper, but if platinum is the same price you might as well use it.
 
with regard to the NGK, is the v power copper, platinum, or standard copper any better than each other? Their cost appears to be within .50 of each other per plug, which seems odd.
I've always used the platinum plugs
 
Also, make sure that all the connections are clean and tight. Vacuum lines are in good condition.
 
in what? your lawnmower?
In my own personal vehicle's, family, friends. Being a professional mechanic for 30 years, this is something that you should know about just because I don't have some old crappy car doesn't mean that I don't have experience working on them.

so you'll work on friends and family cars but you won't buy a project car?

got it.

I've said from the very beginning that I don't want a project car, what I mean by one and what you mean by a project car is to different things. The dart wagon you bought, that's what I consider a project car. One that needs minor things but is driveable is not a project car
 
It's hard to get you guys to understand what a project car actually is, how sad

Stay with Champion plugs. The No Good Kind are harder to read and the heat ranges are whacked.

If it’s a small block and under 10:1 you need a Champion RC12YC.

Rare earth metal plugs are for suckers. Pass on that junk.

When I was a young man, my dad would tan my hide, if I bought anything other than a champion.
 
That’s the same reason I still run them! Haha. I believe mine are currently the 14 series though and not the 12. Is there an actual functional difference in a street car between the two?


The 12 is a range colder than the 14. Thats the only difference except you can get an N series plug that has a 13/16 hex or the C series plug, which has the much nicer 5/8 hex.

So an RN14YC is the exact same plug as the RC14YC except the C series has a 5/8 hex. Much nicer to use.
 
I quit using champion plugs because they foul out so easily. They are really bad in a 2 cycle engine where there's high rpm's. Just my experience

Plugs dont foul unless the tuneup is wrong. I ran the same plug in multiple bikes for years and never fouled one.

Don’t blame the plug if your tune up blows chunks.
