well i posted a few days ago and never got a response about the spark plugs, but i replaced the opti with msd, the coil with msd, and the plugwires with msd. i am replacing the plugs with ngk g-power with the parts store says that these plugs need to be set at .050'' with this engine. now with that new msd set up i got what should i set them at?, i was thinking .042'' cause thats what my father told me to run. also the only reponsewas fsm said .032''

Assuming that all is pretty much stock internally I'd run .045-.050. If you are running forced induction you need more current and voltage to jump the gap as boost pressure goes up so you would needto run a smaller gap somewhere around .035-.040
