30k mile 258 w/ Holley carb value?

I'm in the middle of a LS V8 swap and my 258 is out. I bought it as a rebuilt long block in 1997. It has a Holley 2 barrel, other than that it's stock with 30k miles and runs perfect. Never driven in the winter so it's clean. It's complete with alternator, power steering pump, distributor, intake/exhaust manifolds, and center force clutch 5k miles ago. It's a good motor and I would call it a waist to leave it in a corner in my shop. Before I pulled the motor I took a video of the engine running and driving, oil pressure, water temp etc. Can anyone give me an idea as to what it might be worth to sell? Thanks.
