Hard to say Larry, people all seem to have different opinions on vintage Hemis. An original 1971 engine, carbs to pan, 100% stock externally, just a grease ball yanked from a car early in it's life, went for 20K this weekend. Most consider a 1966 engine (usually considered the least desirable year) in similar shape to be worth roughly half that, so IMO, somewhere in that range would be about right. It's certainly a premium piece (if all or mostly there and unmolested) to the right guy.
