Back in the day they were 11's I believe for the Six Barrel 440's, but I don't think they are available anymore.

I used to run the 11's in both my 440 8 bbl Charger and my wife's big block 383 Dart but that heat range started getting scarce in the 90's . So I'd keep a couple of sets in my tool box for when we knew we were going to be running either one of the cars hard on any certain occasion . The colder plug was definitely a better choice performance wise . I wouldn't mind trying to hunt down a set and trying them in the Warlock when it finally hit's the streets .
