A 3800 swap requires a few extra things. Can't remember them all but I know that you'll need a wiring harness from a 98-99 Monte Z34 or Lumina LTZ. But like l67ss said, if you want a 3400, I'm pretty sure it's as easy as pulling the 3100 out and putting the 3400 in (as long as the 3400 is from a w-body).

I agree, a 3100-to-3400 swap should be easiest (and there is a member who posts from time to time who is actively doing a swap now). Here are a couple of links in our tech info section to info about this type of swap:
