Iron intake ID help needed

[MoparBill]

I have a couple of cast iron intakes that have been kicking around my garage for many years now and the part #s don't come up on any reference books I have. Can any of you help me ID them?

It's been way too long for me to remember what I took them off or how I got them; I started tagging everything a few years back to help with this!

Bill, the first number comes up as a 400 4 bbl intake used from 75 to 76. The second is a 440 intake also used in the 70's.
