Read the thread in it’s entirety, we’ve been talking about it for 3 pages now. Maybe click on a few of the links that have been posted. There is a lot of valuable information being discussed here by myself and other members much smarter than I am. I do not pretend to know everything (hence this entire thread) and will not try to convince you as such. The mark on the tip of three of my plugs seems to be an indication of some type of weird chamber/burn anomaly, or maybe plug index related. The timing mark as I’ve stated multiple times is down near where the groundstap is welded to the thread base. Once again we ran timing sweeps (if you don’t know what that means please look it up) on the dyno and watched the power go away and come back on either side of 30-31 degrees. Hopefully you see this as educational and not picking you out of the group as that is not my intention. But I think there is an opportunity here for all of us to learn something.
