400cu in TQ intake w/o EGR Valve mount

I'm cleaning house. I see that cast iron Thermo Quad intakes everywhere and are a dime a dozen. I don't think its worth my effort to try to sell and ship cast iron intakes, but I do have this one. I guess that it is an early 400 (1972 or 3?) intake as it does not have the mount for the EGR valve. Is this worth trying to sell?

you may get a better reply on the WIW and EBAY forum.
as to the desirability of that intake, it would depend on the cast dates to someone restoring a 72/73 "?????".
although it is heave, you "might" be able to fit that into a USPS flat rate "game" box.

Thanks. I did look at the Ebay/WIW forum - seems like just cars
