The '38 model year is an odd choice for the end of the coverage. The end of the '39 model year strikes me as a better choice, but they must have had '38 in mind from the beginning as no '39 model engineering drawings or releases were in their accumulated small mountain of Ford engineering document copies.

Both George DeAngelis and Ed Francis (fellow Ford employees) were likely best known in Model A circles and their book on that subject is, as I understand it, the definitive work for those Fords. Prior to and during the writing of the V8 book, neither George or Ed had much hands-on experience with its subject matter, so there are a few (very few) errors where a long lost drawing or release form had gone astray, thereby misleading the authors. After the book was finished, they both acquired Fords of the '32-'38 era to go with their Model As.
