Unhappy Bad Ignition Problem

So i took the SS to the track today and ran a best of 15.5 @ 90. So im like WTF! I was so pissed i was about to drive it off a bridge. My mechanic that tunes it and the shop that built it said it would easily run 13s. I gave my friend a ride when i first got it, and he told me it pulls like this 13 second C5 he got a ride in. I gave him a ride after the track, and he said it was noticeably slower. I knew there was something going on. I got home and popped the hood. It was really dark, then i saw it. Each plug was arching where it meets the head. I dont know if i would call it an arc, cause you cant see an actual spark, but it is a blue glow. Also when i pulled the plugs to check, there was oil on the threads. Im not sure if that is a related problem though. I know if there is oil getting into the combustion chamber it isnt much cause it doesnt smoke at all.


Other info is i am running an MSD 6AL, Accel HEI coil, and Accel Shorty plugs gapped at 45 (only ones that clear my headers), the wires are MSD 8.5 "Race Tailored" wires.

I hope someone can help me out here cause i need to get my low 13s back...this was an embarassing night.

PS you can check the rest of the specs if you look at my first post

thanks again

Apply dielectric grease to every boot and plug. That will eliminate a possibility that the ingnition is grounding. With higher spark energy it's a commen problem. You'll need to look closely, Seeing the spark energy through the plug boot is normal but seeing the spark arc ground is not.

Really try the dielectric grease, it helps alot. The MSD-6 puts out a lot of power and will jump to ground if you give it the slightest chance. Remove your plugs and check them with a 8 to 10 power magnifying glass for cracks. Often time with difficult to install plugs the insulator will get cracked from the socket not being perfectly square to the plug. Over torqueing can also crack the plug.

i tried the dielectric grease and they still glow. It really is not missing though, still very smooth. But im just wondering if it is not getting all the power it could

Don't worry about it. You have already overkilled the park energy anyway. Worry bout it over 12 CR.

then im going to beleve the lack of power is due to an old 600cfm holley (lil ecomomy carb) and the restrictive intake
