Did not seem like a total plug failure but small flakes missing. Also did not see any specks from detonation. Am I wrong in thinking I may be running to hot of a plug? The base of the porcelain looks a bit lean but not too bad. 11:1 Stealth headed 440 EFI Currently run an NGK BCPES-6 plug. I have some NGK with a colder 7 range in the shop. Just wanted to verify that the plug heat range may be causing this. 1968 Pro-Touring Dodge Charger *2011 Optima Ultimate Street Car Challenge Invitee http://www.popularhotrodding.com/features/1203phr_1968_dodge_charger/index.html

Maybe go to -8's if I still signs of them being too hot. 1968 Pro-Touring Dodge Charger *2011 Optima Ultimate Street Car Challenge Invitee http://www.popularhotrodding.com/features/1203phr_1968_dodge_charger/index.html

The ground strap has minimal color change and the porcelain is showing signs of damage/stress, so I think I am on the right track with the colder plug. 1968 Pro-Touring Dodge Charger *2011 Optima Ultimate Street Car Challenge Invitee http://www.popularhotrodding.com/features/1203phr_1968_dodge_charger/index.html

I know of a few 8-second street cars but ALL of em run power adders so not as special to me as n/a stuff. 72 Dart 470 n/a BB stroker street car `THUMPER`...Check me out on FB Dominic Thumper for videos and lots of carb pics......760-900-3895.....
