Looking for opinions on Mopar M1 single plane intake

Thanks. I was trying to find the mopar M1 single plane for magnum heads, but every one I found was going for $600 or more. Not really wanting to spend that kind of money for one. I found a guy that was needing money, so I bought his Indy 360 magnum intake for $300 shipped. The intake is brand new never been bolted on a engine. I finally got lucky for once. Lol

Is the mag M1 single plane really going for that much, I just sold one for $250.00.
