With castings, the selection of aluminum to be used is different, as compared to the aluminum in the machining process you are using ?

Yes! Casting alloys and machining alloys are very different! We used 319 some time ago for our differentials and we didn't like it at all. The strength with 319 is less than 356T-6 and we didn't like how it machined. 319 is not heat treated. It is used "as cast" therefore, it is cheaper than 356T-6 (which I imagine is why Ford has switched to that alloy).
Now, Ford has VAST experience casting. Anything they cast will be far better than anything a small casting house can produce with small casting runs.
