: Big Block Guys: What plugs are you running?

The car is loading up and I think it's the plugs. I'm waiting for the car to cool and I'm going to pull them. The car is loading up upon start up and is fine after about 30seconds. I'm running Accel Shorty header plugs but don't think they are cutting it. My other Big Block would only run on Autolites so I may try that, I'm just curious what you guys are running??

I pulled the plugs they are black as coal, no doubt the plugs are the culprit. Send me your recommendations. :D
