I would recommend this book...
Amazon.com: How to Rebuild Your Small-Block Chevy... When I was seventeen I rebuilt my first small chevy and I didn't know what a thrust button was either.
( It's a metal washer that you weld on to the timing cover to keep the cam from walking bty.) With this book and a good machine shop I had a successful build. It has detailed info and plenty of pics. Also if your going with a hipo motor then pickup a copy of
Amazon.com: How to Hotrod Small-Block Chevys:... Good luck with your build.
