Plug read--detailed pictures

Fuel is Q16. 1150 dominator with 94 jets square. Ignition MSD 7AL2 plus. 16:1 comp 572, P51 cylinder heads. Total timing 32 degrees, crank trigger. Thinking about going back down to 30 degrees. How do these plugs look? The sprekles look like slight detonation to me.

maybe some kind of oil contamination ...... ???

one a diff heat range then the other 2?

were these from a full pass,or a wot shut off?

those plugs look to have sevral runs on them and the timeing mark on the strap looks to be missing?

They dont look like a 1 pass deal.

thats what i thought , id like to see them after just one pass

Yeah these have 7 passes on them.

The timing mark you are speaking of, where should it be if it was good?

Should see a line in about the middle of the strap, typicaly indicates the timing is about right for the plug.

i'd put more fuel to it...........a lot more. rich wont kill it,lean will. who's 1150?

Rotate the plugs 90*.....that way we can see the heat line on the ground wire better.

I can kinda see what looks like a timing mark on the second plug. It looks to be toward the top of the bend(I could be imagining things). It's hard to get a good read for tuning after 7 passes, especially if your driving the car to the lanes and back from the pass.

fresh plugs, more fuel, shutdown, tow back,re-check

yep, I purchased a jet kit from 94-102. I am going to a private track day next week.
