Its always hard to get back out of an engine what you put into it. A 194 is probably the least desirable engine because everyone wants to go bigger like to a 250 or 292. Not saying the 194 isn't a worthy engine, its just going to be harder to sell a rebuilt 194 vs. a rebuilt 250 or 292.
The 250 should sell fairly fast, but I'm not sure on the 194. Hey it's good to hear from you again. I watched all the videos on this car and still wish for more. How's it been running?
