Engine Description Manual
These drawings/notes are from the BOC Engine Description Manual as scanned by Ed Baker. He has a copy of a copy of the manual and his copies are not very clear-especially when it comes to the text. At one time, one could buy Description/Assembly Manuals that GM prepared for the factory to use as a guideline for engine and car assembly. I have them for Camaros, but, I have never seen one for our cars before. If one takes the time, I think most of the text will be decipherable. Hopefully, these will provide assistance with many of the questions that arise. This is not an engine assembly manual, but, rather, a depiction of how components are fitted together with some assembly notes.
I am going to try to group pages of a common nature on single pages as denoted in the below links.
