I would like to know:
1. what plugs i need for my current setup as well as gap
2. i plan on having my novi 1000 after cruise, what spark plug should i get with that and at what gap? thanks tom

For your N/A setup run Autolite 3924's. Gapped at .45.
When you get a supercharger go with 3923's gapped at .35.

ok, if i get my msd ignition 6a soon, would that change my gap?

You could probably get away with running a little more gap with the MSD. Maybe .05 to .10 depending on your car and type of fuel.
