The 350 I picked up was working, but i decided to have it rebuilt as I did not know what kind of shape it was really in. Turned out one of the intake valves was leaking and the pistons were shot. Glad I spent the bucks to get it done.
I just started a thread with my truck if you are interested in checking it out. It needs inner rocker panels, and has rust spots in some difficult areas under the hood.
