"How the heck can a 950cc engine have the same air filter as a 1700 BB Tbird? Wouldn't you think the Speedmaster has more than enough air and maybe the TBird not enough? There is lots of talk about air kits and increasing airflow - but I'm thinking perhaps that maybe that isn't such a big deal as we think it might be."

Its not just as simple as how much air a system can let in. Sometimes air speed (velocity) plays a bigger part of what design can be used.
Yes in the case of the speedmaster I would also guess the limiting factor is the heads/valves/cams and exhaust.
