Now that my 6 barrel is working, I’m ready to sell my intake. It’s a vintage Weiand low profile dual plane for a 440. All the threads are good but note there is a 3/4” long hairline crack in the rear vacuum port. See pic. Also see the hot rod article by Steve Dulcich describing its performance and how it allows clearance for air grabbers too. these are discontinued and hard to find. I ran this with a 1/2” spacer and air grabber air cleaner and hood clearance was good. $250 plus the ride.
