340 intake on a 318?

Makes me wonder why Chrysler decided to foot the bill to make 318 4 bbl intakes when they already had the 360 4 bbl intakes on the shelf. Same thing with the 2bbl's. There had to be something different that warranted casting a new manifold. Later on of course, they used the same manifold, but, the ports between the two heads were a lot closer in size.

Have you ever SEEN one IN PERSON that had 318 size ports? I've not. That doesn't mean anything, but I've never in my life seen one and I've pull a good many off in junkyards. Always had the 340/360 port size. I've seen some the casting number decoded to "318" but they still had the large port size.
