From Wikipedia, and with everything I keep learning about AMC, I take everything with a grain of salt and nothing everything is up for discussion.
Holmes Foundry, Ltd. – AMC's block-casting foundry was a major AMC factory which is now completely obliterated. Holmes had its main office and foundry at 200 Exmouth Street, Sarnia, Ontario, Canada. Holmes was established in 1918, by Mr. J. S. Blunt, and was called Holmes Blunt Limited. In the early years, Ford Motor Company contracted the plant for a steady supply of engine casting blocks. This factory had a reputation locally as a dirty, dangerous place to work. The company had three divisions, all operating on one site at the edge of Sarnia. Beginning in 1962, AMC contracted with Holmes Foundry to supply AMC with cylinder block castings. American Motors acquired 25% interest in the foundry in January 1966. In July 1970, AMC acquired 100% of Holmes Foundry through an exchange of shares, making it a wholly owned subsidiary. However, it was not until October 1981 that Holmes Foundry finally became a Division of American Motors, Canada. As part of its acquisition of AMC in 1987, Chrysler Corporation took ownership of the Holmes facility and its manufacturing business, but closed the operation on September 16, 1988. The industrial facilities were cleaned of their environmental contaminants in 2005, in preparation for a new highway interchange to be built on the site. |

When I was Parts Manager at Indian Village AMC/Jeep in Clarksville, IN in 1979-'80, we got in a new manifold for a Jeep six [I've since forgotten if it was an intake or an exhaust]. The IH logo was plainly cast into this manifold.
That said, that was the ONLY instance I ever saw of an IH casting mark on an AMC part.

I remember seeing a newspaper article about how AMC was casting blocks for Ford in 1968. Ford had AMC cast blocks to help catch up production after it's 1967 labor strike. I believe it was the Holmes Foundry that was mentioned. Can anyone substantiate? |

The first I was ever aware of different materials was when I had my friends shop rebuild my 343 in the early 70s. It was the first AMC they had done and he was amazed at the casting and had to use different stones in the Sunnen honing machine. He was very impressed with it and stopped razing me about my Rambler junk. The other interesting thing was that they cross drilled the crank and screwed it up, so they had to buy me a new crank. Without knowing the difference, they got one of the rare forged 343 cranks.

I looked at my 360 blue print with the last date of 7-21-1990. On the date of 1/31/1978 the detailed info that was posted earlier of the material content was removed.

CFD block, very nice casting, you can see how much material is there by the nice machined lifter bore tops and valley machining for push rod clearance. Here you see the non CFD casting (backwards number at bellhousing. You see the top of lifters are not machined because there was not enough mat to do it, as the push rod clearance at valley is not needed, core shift is pretty bad and you can see a drastic change in the color of casting.

My block is cast in CFD and the core shift is near perfect.
It's a 1975 of unknown application. It came with a Ford Motorcraft
4bbl carb and iron manifold. Can't say for sure where it
came from since it appears to be a factory .010 over bore re-man.
4.175 bores. Two bores are rough and it may need .045 over to clean
but otherwise it appears to be a keeper.
Came with "502" heads.
