so i'm in the process of putting everything back on to my long block for install into my 00 mustang. Current set up is an 8.5:1 compression DOHC 4.6 with a vortech v2 blower @ around 16-18lbs. I've heard good things about ngk t6 plugs for supercharged cars, but what should I gap them to at that boost level? i've heard conflicting advice. any ideas? thanks in advance.:beer:
