What’s a 360 worth

I can’t find the blocks and cranks for 50.00 like I did a few years ago. But then again I quit looking and buying them as I’m stocked up. I’m betting I could probably find one for 250.00 today if I really needed one. I was called yesterday asking if I needed a 904. He’s pissed off over an ongoing leak and bought a 4 speed. Lol
