What is it worth? Super Six Intake?

I have a 2bbl intake that I bought off of eBay years ago to upgrade and add some guts to a slant six I have in a 64 Barracuda. Plans have changed and the 64 will go to someone without the upgrade, as I have a 74 Charger, 72 Sebring Plus and 71 Challenger in line ahead of it for restoration this summer.

Any idea what a 2bbl, 225, like-new Mopar intake is worth for someone who wants to keep the Leaning Tower of Power, but yearns for a little more guts?

Thanks
