Through a few hours of research on the internet, the dubious conclusion of "maybe" has been reached. It seems the original 6.9ltr, and 7.3ltr diesel engines were developed from this gasoline engine casting, but I've not been able to ascertain whether the block rear bolting pattern is the same. The International T444 series is basically the same and is drilled and tapped for an SAE flywheel housing to affix, or the Ford housing, but I cannot verify if the blocks destined for Ford trucks are the same. I've seen many OEM applications have slight differences to protect their interests though the basic structure is the same over many applications. As example, the casting bosses may be present, but not drilled and tapped in one application, but that operation completed for another with differing part numbers for the two differences.
Anyways, I want to repower my old air compressor from it's current gasoline Continental B-427 flathead six, to something more fuel efficient. This 7.3ltr "Power Stroke" engine weighs about the same and runs like a top. The truck is beyond repair as rusted badly.
Best way to prove it is pull two engines I suppose. Neither is a problem as I have a viable place for the 446 engine to go if cannot be used, and the 7.3ltr engine has strong possiblilty of repurpose should these two not go together easily.
