383 Air Grabber on 440?

See the pictures I posted above. I borrowed a 440 base from a friend of mine and it hit the hood of my old 67 Dart with no gaskets in the engine (no head gaskets, no intake gasket, no carb gasket). The 440 unit is much harder to find and much more expensive. Since it still didn't fit, I cut down the neck on the 383 base. I had the ring welded back in because of the lip and locating tabs.
