7.3 Motor mount replacement Q's
Who's done them, and how did you do it?
I was under the impression you had enough space to lift the motor as it sits to gain the room needed to do the swap. I did not have that kind of success.
I removed the 4 large 21mm (L&R) nuts securing the mounts to the cross member, loosened the 2 drivers mount 13mm bolts, I removed the 2 tranny mount 21mm nuts, I was only able to raise the engine a few inches. When I let it rest back down, it did not settle into the same place, I had to raise the pass side to re-center the engine back on the cross member. For now I just put it all back together.
It looks like from what I'm reading and seeing, the CAC pipes have to come off, the spider has to come off, possibly the starter, and front drive shaft too. And maybe the the transmission cross-member should be removed and the tail supported separately?
Funny, I only found instructions in the shop manual for the 5.4, and V10 mounts. I might cross post in the 7.3 forum...

Calling @SkySkiJason ....he will know.
That said, lifting the engine enough to get the studs for those 21mm nuts out of the crossmember is all you should need. Unbolt the (3) motor mount bolts to block and you should be able to slide the mounts out of there??

No failure that I know of, I just want them replaced. The mounts are fastened to the block mounts, the block mounts are impossible to get to, but the mount to block bolts are doable. I think I'll need to remove a few things like the CAC pipes so I can get the motor high enough. This is the only video I found, which is helpful.

What I think I saw was the 2 bolts in each crossmember which are part of the mounts, and 4 bolts 13mm holding the top plate of the mount to what appeared to be an angled bracket which was bolted to the block. I'll dig into this after Halloween.
