Thanks Don. I'm going to see where that guy lives and maybe take a look at it this weekend. I'll try and see the other "rebuilt" one too and see if they're worth what the owners are asking.
One of the local rebuilders I've found said he'd check out the 216 block and head for cracks or any other flaws that would make it not rebuildable for about $100. I think I'm going to do that since I'm going to remove it anyway to do the rest of the work.
