I think you are going to need to give alot more info, IE. what comp ratio,are you running the nitrous or not. what do run the timing at? do you run a timing retard if you are running nitrous? how much nos. what kind of dist you running msd or mag system. what fuel are you running ?
whats going on with the plugs that you have tried and what do they look like?
The more info you give the better a shot at getting good info back to you.

No Nitrous
32 degrees
MSD 6 with Pro Billet
Pump 91
Current plugs were hand me down from a blown 468 running a 200 shot. I can not find the plugs that were run in the 496, while it was a 454, so I do not have a baseline idea of what plug to start with.

Jason,, did some reading on Autolite racing plugs just now,, AR13 is only one step colder than the 23 I mentioned to you on the phone. You can probably run more than 32 degrees of timing, maybe try 34 or 36 degrees I think.
