im wondering if i should run a different type or heat range of plugs in my 460? ive got almost 11:1 compression, ported d3 heads, a big cam and the various other bolt ons. right now i have stock autolite plugs in it, i think 24 is the number, im not sure.
I think you are safe starting with 24s. Fire it up and run it, then read the plugs and go from there.
