Reading E3 spark plugs
Last plug replacement I decided to try the E3s. This is in a 6-71-huffed 355 SBC with 2x Edel 1405s tuned a little rich, Comp "blower" cam, MSD 6AL (5600 pill) & billet distro in a T-bucket (click avatar for a bigger pic). I don't drive this car hard at all, but will do the occasional rolling burn-out. The plugs have a little under 2,000 miles on them. Now I know how to read regular plugs, but I'm having a hard time figuring out what these are telling me. The electrodes look rusty. I just drove the car yesterday afternoon and it's running great. BTW, the 1-3-5-7 plugs look exactly the same. What do you all think? (BTW the stuff that looks like carbon build-up at the base of the threads is copper anti-seize)
