Another Casting Decoding

[scottm]

I received this email request...

Can you please tell me what I have, Intake manifold is 155473-1 and the exhaust manifold says 1531592-ml and has a tag that says 7-29.

Does anyone have any idea what these are?
From the approximate casting range, I would
say they are something like DeSotos or small
Hemis of some kind. Anyone know for sure?
