Good running 400, 430 or 455 engines

Looking for a good running (preferably a 400) or 430, 455 engines. I don't have time/money at the moment to finish the rebuild on my original engine from my '67 GS400. I'm hoping to drop in a good big block so I can drive it around until I get my original engine going.
I can't afford to have anything shipped so I'm interested only in Washington, British Columbia or Western Oregon locations.

Cheers,

 

Todd,
