Should I or should I not even bother...

to try to get this 292 running. This thing has sat out in the elments for 2 and half years just the way it appears in the pics. I tried to get the engine to spin but to no avail. So I cleaned around all the plugs and vacuumed all the sand and rust and then pulled all the plugs and squirted about 3 oz's of mistery oil in each cylinder to see if the rings would break free. I'm gonna let it soak until next saturday and try to spin the motor again. If the motor spins I was thinking of trying to get it started and see how it runs. Now obviously this engine is going to a machine shop and being totally rebuilt but am I stupid for trying to get it running just to see how it is? If I can get the rings free and I do get it started am I just taking a big risk on cracking the block and destroying this engine?
