Anyway that is NOT an Engine Assembly Manual, it's an Engine Description Manual. Details are in the blurb on page 5.
And at that, it starts with what was called a "partial engine," so it doesn't cover the block internals (camshaft, rotating assembly).
EDIT: "Engine Description Manual" may have just been a new name for the same book. The '85 version seems to have been titled "Engine Assembly Manual," but with pretty much the same kind of content and nothing more, from what little I've seen of it.
