have you used the search feature on this site? There is alot of info in here. There is a site called www.TPIparts.net ,go to it and check around.
Other than what you already know, the swap isn't hard at all. You may want to port out the intake. The 350 is going to need more air at high rpm's. If everything is stock on the 350 you should be fine though. I took a grinder and carbide bit and removed all the raised casting materials on the inside of the lower intake runners, plus a little more.
