Late 340 exh. manifold research

Professor Fate said

I *believe* it's a 3418623- should be a common number shared with other applications beside the A body. Uses a common center port and bell exhaust unlike earlier 340 RH manifolds.

Thanks. Thats the same number I saw that goes with a 1973 340 manifold but since learning this RH manifold is 360 I was unsure. I was using the exhaust manifold thread through the search function but 360 manifold listings were incomplete.
