If you haven't done it yet, I would suggest again that you order the GM factory service manual on CD that Brett sells on this site and also pick up a couple of engine rebuild books for good measure to help you get an idea of what you are dealing with.
And the easiest thing for you to do is use the internet. Do some searchs on the web, as well as here, and read everything you can get your hands on reagrding T/A's, engines, turbo units, restoration companies, etc....it WILL help. The info isn't going to just fall into your lap...you're going to have to do some research to find all the answers you need for your project. Good luck.
