What's it worth

I looked at a built 225/ today. It has a Clifford 4 bbl intake, true split headers and is supposed to have the head shaved and bigger valves. No carb but it had a Holley 650 on it when it was in a 70's Dodge shorty van. Motor was built about 20 years ago but has less than 800 miles on it. Been hanging on an engine stand for about 16 years. Of all things, it had a GM 4 speed mated to it that comes with it. Thoughts?
