I'm swapping a 6.0 in my 97 now, and I am using dirty ding motor mounts. You can repin your factory harness to the new 411 computer and just add 10 wires for the coils and another for the knock sensors. Also you will need to cut your one big injector plug off and add the 8 injector plug ins. You can still use the drive by cable factor throttle body if you want to also. It's not beat as hard as it sounds, pm lextech if you want more info on the wiring.

Here is what I did.

Read this over and over again:
OBS to LSx conversion

Then read the pages in this that correspond to your year donor harness:
Wiring Harness Information

Then read every thread you can possibly find on swaps. Google helps with this. I can share my bookmarks, but I can't from the machine I am on now. PM me tomorrow or late tonight to remind me and I'll post a link to them here.

Finally figured out how to copy a lot of links at once. These may not all be applicable to you, but I am posting everything I have even remotely related to doing the engine swap.
