Chris, if you want good books, then get the best ones out there. Contact Reher & Morrison Racing Engines. I have the text books that they use in there engine building school. There are two books, lower engine assembly, and upper engine assembly, and will cost you approx $100.00 for the pair of books. These engine books are the BEST. Buy them for your library if you are serious about this. If you got more money you can go to the engine building school that they have and get these books as part of the price to go to the school. If you really want to build your own engines, then these books are a must.
