A question of value

what's the value of


An "A" code 289, complete with buddy bar Cobra valve covers, stock 4V carb, with tag, and intake tag? I have the gold air cleaner, or most of it, and the original distributor.
The only thing I don't have is the orginal oil pan. ( I think. I may have it too.)

The engine is from the 65 Ranchero I had a while ago. The motor turns over by hand, but feels sloppy, like it has a spun bearing. I have it at home on a stand.
I think that with the tags, having not been bored, even with the spun bearing, this assembly is worth at least 700.00

How far off am I, and why?

I didn't see any damage to the block, it's just when you turn the dampner it feels like something is 'loose', or spun, maybe.
I know to replace the valve covers will be around two hundred, the intake when cleaned and painted is worth a hundred, the carb is a complete rebuildable core, and I've seen similar ones to mine sell for over a hundred.
As a collection of parts, I think it's worth more.
If I parted out the motor, I can see not getting 700.00 for it, but with everything still 'there', I think it's worth more than 200.00.
Oh well. Not really motivated to sell it off yet.
