I always comb swap meets for old books, theres a mixture of good info and stuff that makes me laugh. Recently I aquired some 60's hot rod books on exhaust and suspension. The suspension book has a passage that describes four wheel drive and ends by saying that it is so complicated it will probably never go into mass production on passanger cars. The exhaust book suggests wrapping the starter and plug wires and just about anything that could be damaged by the heat with asbestos. But for the most part a large portion of the info is good, plus they are usually dirt cheap.

That pic is way cool, makes me wish I had an old inline eight cylinder to work on. Oh well, I can wait a bit.
