this is from another forum with the same question
"NONE of them are perfect. Some are good but old and outdated. Others are newer but missing some critical info.
In short, be prepared to buy SEVERAL books to get a remotely-complete picture.
In my library:
How to Hot Rod Big-Block Chevys (Bill Fisher)
How to Rebuild Big Block Chevys (Tom Wilson)
How to Build Max-Performance Chevy Rat Motors (Ed Staffel)
How to Build Max-Performance Chevy Big-Blocks on a Budget (David Vizard)
How to Build Monster Chevy Big Blocks (Hot Rod magazine)
How to Build and Modify Chevrolet Big Block Engines (Tom Currao)
Big Block Chevy Performance (Dave Emanuel)
Big Block Chevy Marine Performance (Dennis Moore)
Chevrolet Power (1st through 6th editions, except 2nd edition) (GM)
Chevrolet Power (7th edition) (HP Books)
Chevrolet Big Block Muscle Cars (Anthony Young) Not a build-it book, but a history of the engines starting in the Fifties. An excellent read!"
