How much is it worth?

Well motors are a tuff sell.

I can tell you I have bought two 360 Mopar Performance crate engines at different times. Both were new never ran one was a LA the other was a Magnum.

Both were advertised for a long time like 4 months. I ended up paying about $2,500 for the LA engine and carb. delivered to me from about 200 miles away by the owner. The Magnum came with trans, convertor, starter, alternator, and even a shifter all new and I bought it for $2,800 however I did have to take it apart for cleaning. It had a little water damage inside the engine.
