If it was cast in 77, it's a local block. In your case, it's a truck chassis assembled here from US-made parts. Ok it's a bit hard to explain but during assembly, the engine number takes on whatever chassis it goes into, regardless of where the engine was made. But the engine number tells us its a US block from a 77 f100? Yet they stopped making them in the usa in 74. I have no idea what vehicle it originally came out of, i removed it from an xb sedan. Yours would definitely be a locally cast block. My 302 clevo came from a 1975 XB ute and was US-cast (very close to the changeover date to Aussie production). The fact that it came from an F100 doesn't mean it has any mechanical significance over one that came from a Falcon, other than perhaps having double fan belt pulleys or whatever other heavy duty items the trucks might have had (dunno exactly). The only differences I can think of are the casting methods and the hardness of the material ie: Aussie blocks used a harder iron. The part number starting with D2 is no indication of country of origin as the Aussie casting has no significant changes from the US one: they are both "square" blocks as opposed to the earlier "D" blocks. US-cast has "CF" (Cleveland Foundry) with the "C" wrapped around the "F". To confirm if it's an Aussie-cast block, it should have a "GF" (Geelong Foundry) in the top of the block next to the oil pressure sender.

L = Broadmeadows (Commercial) Ass'y Plant Going off what info you have, it should read something like: The last digit on the engine/chassis number should tell you what engine it is (pre- or post- ADR36 V8). All US "cleveland" type engines cast after that were 400s or 351Ms.įord H/D commercials have a different kind of chassis number to a Falcon, so your engine number starting with "A" is correct for an F-series.

If it's from a 1977 F100 it won't be a US-cast 351C, as they stopped making them in the States after 74.
