There's value in everything...price depend on timing...problem with the '42-47's is they're just not as appealing as the 40/41, or earlier models...best thing to do (IMO) is get it running and driving, then look for selling it off.
Ebay is a place to start to get an idea...fordbarn.com is good too.
Also, join the HAMB (Jalopyjournal.com), someone might think it'd be cool to turn into a car hauler/etc with.
FWIW, ANYTHING old, that runs and drives is worth a grand, add to it your FH V8, if lowmilage and runs well, you could get a grand just for it.
Pics of the truck (both good and bad) will really help the sale, so don't be shy with the digi-cam
