there are a lot of discussions on this topic in these forums. This comes up frequently. Have you tried to search the forums? I don't know of a "tell it all" website on this, but there is a lot of info on the web on this type of swap, if you try to do a google search, you may find a lot there.
The short version is make sure you have a donor car if you plan on going fuel injected. If you are doing a carb'd swap - its as easy as dropping in the motor and trans, finding a decent rear and upgrade fuel delivery & cooling systems.
If you have more specific ?'s, i can try to help you out, as i'm in the middle of the world's slowest swap myself. PM me if you are in a bind.
