In fact that car had an original 3 bearing IMS installed by LN Engineering.

Some of the special tools my buddy built himself, others we purchased.

I don't know if there is anything specifically tricky if you have experience doing engine work -- with the exception of the insertion of the wrist pins for the second set of cylinders. This is performed blind, and by feel.

Funny you should mention the wrist pins, I felt pretty confident up until I saw the YouTube video of them being installed, looks very challenging but doable with either the proper tool or a fabricated one.
How do you know if the piston and connecting rod are lined up before inserting the wrist pin?

Pre position the connecting rod, as I recall that is BDC. Then line up the piston compress the rings and install it in the bore. I had everything slopped in Mobil1. Gently tap the piston towards the rod while watching through the pin / clip installation hole. When it got close I cheated to get the final alignment by moving the crankshaft slightly. I also made my own wrist pin / clip installation tool with 3/4 electrical conduit and socket extensions.

The hardest part was getting the wrist pin clips into the installation tool without over bending them. I ended up using a piece of wood and a screwdriver. It was not graceful. The glenn986 video shows the tool he made to do this which was graceful.
