I'm prepping for a swap using an older TBI motor. Part of my prep is reading a book from Jags That Run about TPI and TBI swaps. I don't know if there is a similar book on the LS motors, but I'd look for one. This book has helped me a great deal knowing what I'm dealing with.
I recently saw a magazine article on replacing a TPI motor with an LS, so the information must be out there. It was in one of the Corvette magazines a few months back.
