1968 to 1973 340 short block or long block

Eastern CT, towards UCONN. Zip is 06237. I'd like $400 for it. It's surface rusty but given the earlier work done to it...
Something to think of though - "if" the block you have is even a little bigger than .060 but passes a sonic test and the bores are round and straight, custom pistons are $8-900. Completely machining another block will run more than that, at least around me.
