I had my hands on one of them at a swap meet years ago. It was an edlebrock dual plane, not a port o sonic though. It was neat, had a big aluminum pan that went right down into the valley and was sealed on both ends. The guy who had it didn't know what the purpose of the big pan was. Ice would make sense, but we thought it was to keep the hot oil away from the bottom of the intake. The new air gap manifolds are kind of the same idea. I've never seen another one, should have bought it just for conversation sake.
