The manifold you want is 3462017 $$$$$, alternative would be a 383 and hope it clears the steering column and box if power steering and I guess you would want to use the spacer that goes on thee right side to get the pipe in the right spot unless you are having custom pipes bent? The good 383 left is 2946729 , or you could try the C body HP 2863409 , it would work in a pinch on a low deck and from the top looks like the same manifold and I want to say it is the manifold that Accurate was modifying and selling.

I have a nice one of the C body manifold and a pair of jet hot coated and ported 383 manifolds
