If there is a Border's bookstore near you go and take a look in the automotive department. There should be several. It is such a popular engine a lot of books have been written on it. I think Peterson Publishing has one based on the many articles they have done with engine builds and testing. Anything by David Vizard is gold. Read the credentials on the back cover about who did the book. That should help you pick a good one.
If you have a used book resale store nearby, like "Half Priced Books" that is also a good place to find what you are looking for and save plenty of cash.
I don't think too many people here read books. I admire your initiative. Research is how to do it. :thumb:
