What’s a 360 worth

parts360 prices are all over the place. i see guys saying that they can't give them away, others are asking stupid money for them. seem like they are selling for anywhere between 100-500 bucks. maybe location has a lot to do with it. they are getting harder to find.
I have a complete 1976 360. It did not come with heads. Turns over easy. I have a set of J heads that I was going to use on it. Motor needs rebuilding, not sure about the heads. $ 400. for both. I also have a 1994 magnum 360, That ran good when pulled. Have computer that came with it. $500. for magnum and computer. I have a garage full of extra 67 parts. I am in Northern, MI. Near Mackinaw bridge. 80000 miles on the magnum.
