I had a '52 truck with a 216 sitting in the driveway for 18 years without ever turning the engine over. As soon as I got gas to the carb, that baby fired right up and idled as smooth as when I shut her down 18 years prior. Those inline six engines want to run. It is up to you to give them what they require to do so.
Don't be so quick to give up on yours.
Compression numbers mean very little on a cold engine.
