I will add mine.
1. 1998 C5 motor with no internal mods yet. My car is a 77 280Z BTW. I used the C5 harness and the C5 underhood fuse block. I used the 99 and up PCM and had to repin the PCM connectors.
2. Auto trans from Fbody with C5 oil pan and pick up tube.
3. Made my own mount and using the C5 biscuit engine mounts. Right now the engine mount is just a 1x3 cross bar that sit on the frame rails. I will find ways to link it to the crossmember later.
4. I used the original C5 headers and modified them to fit, Honda alternator, C5 air intake duct route over the radiator, Electric water pump, EFI live to program the PCM .. etc... There are plenty of modifications on this engine swap and they are all documented on my homepage.
5. I don't remember when I started the swap but I completed the motor swap in August 2006.
6. Irrelevant to the motor swap.
I've also done an LS1 swap for a friend of mine on his 77 280Z. For this swap I used the JCI mounts and the stock wiring harness. Pictures are on my web site also.
