For a basic teardown and rebuild book for LA small block
"How to rebuild your small block Mopar"

"How to modify your Mopar Magnum" for magnum style engine and parts

Honestly there is not much new with the small block stuff. It has mostly all been done with a lot of tried and true builds already posted here.

Best advice is to post what type of build you want to do and you will get some good advice from this forum.
