Re: what spark plugs
You should probably save your money and not buy an msd 6a box. You can get a lot more performance for the money.
You are looking for AC Delco R45TS plugs.

I would actually run the Rapidfires of the same plug. The Rapidfire has a projected fine wire inner tip, that gives the flame kernal more area to travel outward.
