Value of 67 Cuda 273/235 no.s matching engine

Maybe I’m in the wrong section. Spoke today with a longtime friend who is thinking about selling a 273/235 out of a 67 Cuda. According to him the engine is complete down to the exhaust manifolds. Valve covers, carb, pulleys, distributor, air cleaner, he says the dizzy and carb still have the tags on them. Was pulled running. He is not selling it as a bolt in and go he is selling it as an engine with no major flaws that needs rings, bearings, gaskets, valve job etc.
I’d really like to know what you think. This is definitely not a fire sale !
