I'm really glad that I read this book before I started building a hot rod. In addition to all of the technical advice, it prompted me to ask myself some important questions about what I really wanted to build. The layout of the book is very good and is very well written and illustrated. Unlike most magazine articles and other books, it even has a pretty thorough listing of parts and prices for a sample hot rod. That gave me a good place to start when I was trying to figure how much my hot rod would cost to build. All in all I would recommend this book to anyone who is interested in building or having a hot rod built.
