Technical cadillac/stude intakes

Did anyone manufacture an aluminum 4-bbl manifold for the 331 Cadillac? I see that Studebaker manifolds can be modified to fit cad engines but what exactly has to be done to make it work?

 

Only one I have seen a picture of was a Cal Connell single 4bbl marine manifold. Factory came out with 4 bbls in 53 or 54 when 4bbl carbs came out. No need for aftermarket to produce. Cad was a year behind Chrysler I think.
Cad can be modified to fit Stude, but I don't think it works the other way around. Whats wrong with the stock 4bbl intake if you are running a single 4bbl?

 

HAMB'er Picasso made his own 6 log Stude. Probably don't help you much, just saying.
