  The giveaway in Chuck's initial post was that the manifold in question was 
made of aluminum. I think everything else in a GM 2-4 setup had cast iron 
intakes.  Secondly, he mentions it came off a small block Chevy engine so that 
eliminates it fitting anything else but a Chevy.  It turns out it's from a '56 
Corvette which makes it pretty desirable.  This low profile manifold allowed the 
carbs and aircleaners to fit under the hood of the Corvette.
