For all engines, not just Chevies
I don't own a Chevy engine, and I have a lot of books about racing engine building and modification (all Fords and Jaguars). Nonetheless, this one is a must have.
There are better suited books if you're just rebuilding a stock engine, but the conceptual explanantions for racing are well explained and very insightful. I would recommend this book to anyone racing and to anyone who's a serious racing geek (me) and just likes technology.
