Mor-Power Aluminum Intake manifold

In my travels yesterday I came across this interesting piece.





Complete with spiral action technology cast into the carb flange. Does anyone know what this is off of?

 

Nope. Any patent numbers cast or stamped in? Searching those might help. Overall dimensions might help too.

 

Mor Power was a Canadian Tire brand name in the fifties and sixties as you no doubt know. But somehow I can't see that as a Canadian Tire part.

Looks like someone went to a lot of trouble to make a hot rod part that didn't work. My guess is it fits on a pre 1963 Chev six but that is only a guess.

Other than that I got nothing.

 

There wasn't anything more obvious for numbers on it (no GM, FoMoCo etc.) no Foundry ID
