I need some help deciphering a couple of my plugs. So yesterday I pulled my plugs in order to replace the inner springs after breaking in the cam and there were 3 that some unusual patterns on them. It was like a perfect deciding line that parted the electrode, half of it had typical carbonate & the other half was a clean as it was when installed.
I've never seen that before, any ideas what that means?
Motor is a 440/Holley Terminator & dual sync distributor, RPM heads, base timing is &18°/32° compression is approximately 10.5, 93 octane, cam is 545 lift 241/247° @.050.
