firebird 400

i'm in the market for a 71 firebird 400. any ideas on where to look for one or how much i might have to pay. i only want it to run and have a straight frame, i don't want it to be perfect.

I know of a 72 Pontiac 400, not the original motor, but it's still impressive. Saw it two days ago.
