well, I bought an engine core (type IV) yesterday. I think it'll provide some good parts despite being locked up. The whole thing wouldn't turn but when I took the valve covers off, the top looked really clean so I handed the guy the cash and took the engine home. We also stopped by the longest yard sale on the way home

I pulled the heads off when I got home to see if I find the rusty pistons and cylinders.... nope those look clean. The heads looked brand new! I took the pistons off and was able to free up the rods on the crank. It appears that the oil/grease (the "keep it lubed until it runs and builds up oil pressure" lube) seized up the bearings. I have been PB blasting the mains trying to loosen them up.
I figure if I can't free the shortblock up, I can always pull Penelope's engine and slap the other P/C and heads on. Well worth the $180 I spent on it
