Fouling plugs??
I have a 4.8 with a set of 241 fbody heads on it. A fresh set of plugs and it runs great, a day or two of driving and then climb on it and it breaks up under full boost. It has a good tune and everything looks good as far as fueling goes. I done a compression test and all cylinders were between 136 and 141 except number 3 and it was 170 :-/
Do you guys have any helpful information for me??

Plug looks great but down deeper on the porcelain, it is really black and appears to have slight cracks. No wetness on the plugs, tip is clean and all plugs have the same look! I am on 13lbs, 6lbs when towing. Thanks in advance!

Ill try it, I assumed the LS ignition system was hit enough that this wouldn't be an issue.
The picture is poor but you can see how the plug gets jet black just below the threads. Thanks guys
