273 Comando - What's it worth?

I guess whenever I see a Commando looking motor I think of my early Barracuda...but now I can plainly see that the engine bay is a second generation a-body engine bay..my mistake.

I have a 318 in my car, dressed up to look like a Commando. None but the most discerning would notice the difference. I painstakingly rounded up all the right parts, throttle linkages, etc....took a few years.
