Have Spark Plugs Improved
In the last 42 years or so? That is the last time I fired this engine. At one time Champions were good for about 7/8 thousand miles,and NGK's would give me about 11/12 thousand between tuneups.I am looking at Champion BPR6EGP's or NGK RN12YC's as I do want to stay with copper.I could go with platinum but then I would have to add an MSD for more power across the electrode.And why can't I get non-resistor plugs today?Sheesh,I ask the counter person and get a blank look like their nose fell off.

Ah yes RR1, I do indeed see that you are a little younger than I am.I always found that if I tuned to the right station I would not hear the buzzzzzzzzzzzz so much.Besides as loud as the exhaust is I can't hear the radio (AM only) anyway.[Now I gotta find baby some new shoes,185x70x15 Vredestin"s,or 180HR15 Michelin XAS:s ?

Sp...sp.... spaarrrrk pl...pluggggs?
What are them?
Just get a cheap plug that is a little hotter than you need... it'll be good. Champions are pretty good, I run them in the hemi, don't have any problems.

Seems like spark plugs started lasting longer when they went to electronic ignition.
Wonder if the newer digital electronic ignitions make spark plugs last even longer.

What used to kill spark plugs was lead fouling from the tetraethyl lead in the gasoline. Since unleaded gas came in, and with tight engines, there really isn't any deposit on the plugs, and electrode erosion is the main mode of failure.

RN12YC is a Champion number, it's what my 87 2.2L Dakota called for. It used oil and the first time I didn't run it long enough to get up to operating temp, it fouled them, and they never would come back with a cleaning. Finally got to the parts store and got Autolites before dad could get me (another) set of friggin Champions, and ran the thing another year and a half on that set, instead of days.
I think they crossed to an Autolite 65.
I haven't used a Champion plug since about early 1998.

Sometime in the early 90's I got bummed because I couldn't find leaded gas anymore for our 57 Buick.

If you continue to run it till you get a misfire, the misfire will be caused by overvoltage destroying something a lot more expensive than a set of spark plugs.

I used 15xx on my trucks years ago.
11xx and 12xx were used on high compression muscle cars many years ago.
I don't care what the champion charts say I use what experience proves.

Somehow I think I am tending toward the NGK"s.Last night I did the second Stromberg HS 4,now for the third and final one.We did mill the head and bump the compression up to about 9.5 and added hardened valve seats.I have no idea what today's "gasoline" is,but it sure ain't what we used to run.
