Advice needed on used crate engine

He emailed me back and said that no one has been inside the engine that he knows of. It was in a Duster that he sold to a friend, and then pulled out of that car later. So basically, I have to take his word that it is a solid engine. He said he would take $450 for it without the valve covers that I didn't want anyway.

I am going to go see it today and pull both valve covers. I should be able to tell a little more about the condition of the engine after looking under there. If everything looks okay, I'll report back later after I go watch the race.
