LS swaps are cake...with icing on em. Like was mentioned before me, you will encounter hiccups, and you will wish you had done something different after you have finished the install. Word of caution tho...If you plan on dropping that truck around a 4/6 drop, DO NOT use the truck LS pan.
Hang out in the LS forum and you will learn a lot, plus there is a FAQ section.
And of course all of us, if asked, will be glad to call and talk to you or send you more detailed pics if you have problems.
