Now that it's officially winter here, and I'm forced to actually work on this book instead of painting or wrenching or taking more pictures for it...
What would you like to see in it? There are at least 3 different types of manuals out there that cover the basics of rebuilding and maintenance, although all have errors and differing omissions. Mine will have the omission of the "F" engines, since I don't have one to rebuild for the book, so maybe I should call this part the "750K1-K6 book"...
I plan on having some theory in it, like specifics about this forced-swirl combustion system, which was novel at the time and has influenced all engines since. And, electrical theory, to hopefully ward off misunderstandings about why this type of alternator system is different from a typical car. And, suspension theory, which no manuals ever cover, maybe tires, too. And, oiling system theory, because these engines oil themselves in many subtle ways that most folks don't realize.
Mixed into the text so far, I have "Performance Tip" where freebie improvements are available for some elbow grease or cheap upgrades of some sort.
Short of turning it into an encyclopedia, what else would y'all like to see?
