There are 3 books you MUST get if you want to do your own build for the first time.

"How to build the smallblock Chevrolet" (Larry Atherton and Larry Schreib) ISBN 0-931472-26-1

"How to build max performance Chevy small blocks on a budget" (David Vizard) ISBN 1-884089-34-8

"How to rebuild your small-block Chevy" (David Vizard) ISBN 1-55788-029-8

The max performance book by Vizard is one of the best books out there. He even gives you 10 different engine combos - with every detail you need - and they are dyno tested.

That's what I suggest you start with. Good luck!
