From what I can tell, the 1UZ-FE and the VH45DE seem to be the same width. Not to get totally off topic, but can anyone confirm that?
I would've thought that the VH be a little wider,
Both are 90deg v8, the VH has bigger bore (so the block could be a little widder...). Plus, the valve angle looks more pronounce on the VH, so the heads could also be a little widder... also the UZ uses a slave cam design, that could help it being a little narrower... on the other side, the vh has less stroke than the UZ, so it's deck height could be a little shorter (but I have no data on both engines deck height)...
But I do agree that looking at the picture, it seams to be very close... hell it's a lot less cramped than a VG30DE
On an other note, the UZ looks a lot better visualy... I have always hated the stupid looking intake manifold on the VH... the UZ looks a lot cleaner
either way. its alot of work
*edit* nevermind the stroke... I had the specs messed in my mind... both engine share the same stroke... well there is a 0.2mm difference

Quick search reveals :
Dimensions: 890 mm(L) x 740 mm(W) x 725 mm(H).
From wikipedia (http://en.wikipedia.org/wiki/Nissan_vh_engine
according to this, the VH should be a little more than 6inch wider... not even close...
