We used a good quality stand built for a big block when we would do the 4.6 32v stuff. The big block stands have a longer front leg and a little wider track.
They are top heavy with all the cams and big heads. As I recall, we had a hard time finding a good set of long bolts to go into the back of the block. That was the only issue. We found something that worked in our stash of 4.6 gear.
That baby will make a real nice conversation piece. Sort of like buying a gun, hope you never have to use it.
