I agree with Onur, however I will try to narrow it to what I would pay and I've bought 4 late 2Fs over the years, last one about 3 years ago.
Mileage is high. Was it running (well) ? When pulled? Was it overheated or burning oil or sucking coolant?
Will all the attachments come with it? (Int/Exh, carb, alt, smog bits, etc ...)
If answer to most of the above is yes and hasn't been overheated or has a cracked head, for example, I'd pay between $400 -$600 if the motor is a core and due for a rebuild. Engine only without attachments, and only as a core $200 or less. But as Onur says, there may be someone who really wants it.
Price will also determine how long it sits on a pallet taking up space in or next to your garage...
