Paging Jim Rhinehart (Rhinodart)

Hey Jim, have question that came up during a recent conversation.

We know that Norm Kraus threw together a 67 Dart with a big block to show the Chrysler execs it could be done. The question is what about the driver side manifold?
Did they hack a magnum manifold to make it work? If so, was it used as a mock-up for the 67 castings?

Figured you would know.
