Yes, a crossram with a single carb, but it's not a GM part.
Edelbrock made a crossram manifold in the 70s and early 80s. I think they quit making them. Anyway, you could get one of two different tops, one for 2x4s and another for a single 4 barrel. I have seen these intakes at swap meets before. They do look really cool, but I always wondered how well they would perform.
Cornholio, the distributor body doesn't have to be installed in any particular position, as long as the rotor is properly indexed.
I suspect you will have a problem with poor fuel distribution once you get your engine running. As I mentioned above, I've seen these intakes before (with the top removed) and they were clearly designed for two carbs.
