Need help finding which spark plug I need to run...
I am running 15#'s of boost (+ or - a few #'s) on my 383 LT1 in my sig. Which Autolite plugs should I be running between the Autolite 3923, and the Autolite 3922? It should be the same heat range as the Autolite 103 but I can't find out which I need. I need the gasketed plug as I have AFR 180 heads.
Can anyone help me out here? I need to find out which I should run between the two ASAP.
Thanks
