I have a 92 5.0 gt with a vortech v2 sq supercharger and brodix heads. Currios on what plug and gap to run. Im running around 15lbs of boost on 93 pump gas. I have msd 6al and msd boost retard.
Any help would be great.

iirc they use a 3924 rec plug normally so i would put a 3924 autolite in it with .028 gap

I have a 1993 Supercharged Mark VIII with a Vortech 7psi. Runs best gaped at .038 stock was .052 and I use one range colder than stock Iridium plugs.
