71 duster at mecum

Okay, just out of curiosity, I have a 1972 Demon 340, originally a 3 speed car, bench seat, cloth, and the old full wheel covers. About to send it to AMD for a restoration, lots of sheetmetal to change, gonna mini tub it with frame connectors. I'm not sure yet what route I'll go engine wise, but it's the original block. Thinking of going a little crazy with it, but still undecided. What might something like that be worth, in the opinion of the members here. Not planning to sell it, just curious.
