1970 model year for the iron manifold. There have been rumors of early 70 models produced with the aluminum manifold. I have never seen one.
I know of a 'Cuda 440+6 with an aluminium intake from factory - the early cars apparently got some leftover parts. I have posted pics in the past of the car - a highly optioned vehicle.1970 model year for the iron manifold. There have been rumors of early 70 models produced with the aluminum manifold.

It seems that any 70 model 6 bbl or six pack produced with an aluminum manifold was for the purpose of depleting inventory. But at the same time it would seem that some aluminum manifolds would need to be held in stock for warrantee reasons, I would think.
Some of the aluminum manifolds were known to crack. I wonder if a iron manifold would have been used as a replacement on a 69 A12. I've never heard of that happening either.
I believe the iron version was a 70' only thing. There will not be any 69 A12 cars with an iron intake (from the factory anyway).

Worst warranty job ever!Friend worked at a dealer and warrantied aluminum manifolds with cast iron ones.
'71 and I believe '72, Chrysler offered a marine six pack (M-440S). Hard to imagine they would park a cast iron anchor under the carbs for a boat application. Then too, it is Chrysler. My marine carb set came with an aluminum intake. I can't say for fact that's how it came from the factory though.It seems that any 70 model 6 bbl or six pack produced with an aluminum manifold was for the purpose of depleting inventory.
