Looking for opinions on Mopar M1 single plane intake

That's one sweet intake manifold... ( reffering to Mopar65 ,picture).
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
