I second what Oil Pan 4 said about the block. Remove the pan and look closely at the webs around the outer bolt holes. Also look closely around the cylinder bottoms. I have one of these blocks that has a small crack at the cylinder bottom due to core shift when the casting was made. This is/was a known problem with these motors. The best blocks are the ones from 82 83 as they have a high Nickle content.
