/6 or v8 swap?

I do have a few slant six engines laying around. But all of them came out of cars that have sat for 20 years or more. Same with a few of the SB engines. So none of them are drop in ready and will at least need opened up to give them a look over and at least a regasket. She's not much on chatting with anyone about anything, at least not random strangers. She and my kids are not really into that, they make me call parts houses, vendors, appointments, etc as I had a very sociable job for many years and can talk about anything with anyone at any time. But a car like this may bring her out of the shell. My oldest son is learning this with his 71 valiant as every car guy that sees it in a parking lot approaches him about it. And he does like to see people interested in it.
