I believe 1970 Camaro's with Holley carbs (Z28, L78) and NA9 California emissions got the 4 port. All others got 3 ports.

A little hard to see the top in this photo, but you can see the 4 hoses going to it:

Thanks to Rick Nelson for the photo.

If you are interested in selling I may know of someone.
