There's tons of info on the LSx Swaps section of this board:

67-72chevytrucks.com/vboard/forumdisplay.php?f=206

All the FAQs are covered. Once you're up to speed on the basics, if you have any super-specific questions, ask over there and you'll probably get a knowledgeable answer. What you're doing is a super-common swap, so shouldn't be too many surprises as long as you do your research.

Looks like it will be cool when done. Have fun!
