Hardblock?

[FINESPLINE]

As time goes by the amount of blocks is drying up so first you have to locate a block. $ Then you have to take it to machine shop for multiple tests to see if the block is useable $$$. If it passes at that point, the block needs to be machined $$$$. Than the block needs to be poured $$. Remachine block $$. Now unless your brother-in -law owns a machine shop this starts getting expensive and time consuming. Maybe you should look into pricing all that was just mentioned versus an aftermarket block. Do the math and see what works for you. Hope you get lucky on the first block. Been there done that. Just my take. Hell, I just put a Dart block in my street hot rod. To old to be dumpster diving for blocks. LOL
