(To preface, yes, I've checked amazon, the local public library, etc.)
I know this one's a
very long shot, but...I'm looking for a book (I
think it was hardcover) that's simply titled "Engines". It's roughly an inch or so thick and consists of individual sections which contain technical data and cut-away black&white drawings (the ones that almost look like actual photos) of American V8 engines, and I believe it covered the `50's through the `70's era. (don't remember if it covered 4/6 cyl's or not).
Unfortunately I can't give any better details, tell you who published it or exactly when it was published as the last time I saw it was in my Jr. High School's library 30+ years ago. (at least that indicates it was published no later than roughly 1980)
Does this ring a bell with anyone?
Thanks as always.
