All the 427s I've ever seen or heard of had aluminum intake manifolds, never an iron one.
The only exception would be the marine and industrial 427's which did come with cast iron intakes. But Bear is right on the 427 automotive application they all were aluminum. Single and dual 4V.
I am looking at the same intake mani here... C7AE-9425-E Mine is date code June 13, 67 and is from a 67 Mercury Marauder FE 410 CID. The 410 is a 428 crank in a 390 block only used iin Mercs 66 and 67. I have this one now bolted to a '65 352CID FE and with the ford 4V the results are excellent. This intake also has the large "S" on a runner
the same intake was used on 427 FE's in the latter sixties as well. Sorry, that's in-correct.
