There's lots of info on this topic here on Moparts (use the search function) and on the bigblockdart.com board. I was convinced to do the 6.1 after seeing some of the bbd posts:
this one first

You can't just "do" this, you should really research it all and completely understand the costs. It's expensive, don't fool yourself.

The above posts are geared towards the A body, so for your B body, just ignore (for the most part) the space limitations those guys have. Check out XV motorsports as well, as they have all sorts of stuff for these swaps.

The Keisler trans swap from auto to 5 speed if you want to so that as well, is $5500. I threw that in for you, since that's the coolest upgrade besides the 6.1 in my opinion. Too bad it's $5500...... but engineering knowledge is king.

Check this one out in the moparts tech archive:
