What it is worth is based off of what you want to use it for and how much work you have to do to get the engine ready. Do you have a camshaft and carburetor for the engine? Does it have everything else besides these two pieces or are you going to have to buy all sorts of accessories as well? Just off the top of my head I would probably pay about $600 for the pieces you mentioned if the entire engine is there minus the carb and camshaft.
