For a swap of this magnitude, I usually vote for obtaining a donor car. Usually wrecked units that took a side/rear hit that were in good condition are favored. I am thinking something like a 97+ supercharged W-body.
That will get you the engine, transmission, computer, axles, mounts, etc.
There will need to be a lot of custom things to make it work, and the amount of info on swaps is relatively rare. Most who do these swaps do not start with "what do I need" and "make me a list". They usually know where to start, but may run in to small details that they are not sure of the best approach to overcome, such as a specific engine mount, which axle to use, etc.
If you really do plan to pull the swap off, you will need to do a bunch of your own research, and formulate your own plan to make it happen. Many people have put the L67 into many things, so there should be plenty of data.
