Hm, I'm not quite sure if I understand your problem. You can simply
connect a file source to the am demod and then to a file sink.

This flowgraph will then run unlimited ('cause no throttle). But that's
OK if the input file is limited in size. Your CPU will be running full
power until there's nothing left to process.
