Hi there....can I get a little help. What do you guys think about the spark plugs.
Fuel, 91 octane, pump gas.
Engine, 472 Hemi, 11 to 1 compression, aluminum heads,
Plugs, Autolite 63.
Timing, total is 30 degree.
What do you think??
Thanks, Troy

Any speckles, black or bright silver, on the porclyn? If so I would be tempted to try some 62s and then take another look after hitting it a WOT  I prefer a cold plug and a lean mixture. I don't have any real experience with a aluminum headed pump gas hemi on the street  though so keep that in mind  I also ran 34 to 36 degrees in the iron headed 426 Hemi I work on

There are no speckles showing and I think the color looks good. I was looking at the ground strap. I thought there was something about where the ground strap changes color but I cant remember what it was.

I likem. Demarcation on the ground strap ( heat range ) looks perfect. Color ring around barrel looks good too.

Once the plug is colored up it is harder to read, try a new set and hit it once at WOT and pull the plugs, look for a very narrow pencil like mark on the ground strap(no color yet on one hit ), You want it in the middle of the bend, if it is not in the middle,IE one third from the body or 1/3 third from the tip, then try a different heat range  do you have a magnifier you can use? I use a 10X dental plug reader It is amazing what you can see with magafication

They look good to me too but new plugs are the only way to be sure.
Why 30°? I would bet 35 or so would be alot better even with 11:1...

Hi Troy, how have you been?
NGK's are preferred because you can see the cadmium burn line on the ground strap. Fuel ring on the porcelain should be mid way up and watch for aluminum on the porcelain as well (detonation)
And one other thing, dont use anti-sieze with a power adder, it will make the motor detonate.

Thanks for all the remarks!
I'm at 30 degrees to be a little on the safe side and it is a stroker motor with a larger stroke...I plan on adding more timing soon. Looking at the plug I thought the timing was close. This is a street,strip car but has not been to the track yet so no passes yet.
Yes that is anti seize on the thread. I use it when running aluminum heads.
