What's it worth - decked DZ block

[markinnaples]

Hello, I finally pulled the 302 out of my Camaro and am planning on selling it.
It's originally a DZ302 dated 5/12/69, but as with so many from back then, it was decked. Still has the 302 crankshaft. Not sure if it's been bored, but it needs rebuilt. I lost a valve that destroyed a piston but did not damage the cylinder all, and the engine never lost oil pressure. I want to sell but have no idea what to price it at. Also includes a set of 492 heads that also need rebuilt.
