If you are talking about the engine block to bell housing or automatic transmission with integral bell, no, they are different.
If you are talking about a manual transmission to a bell, then they are the same.

If you are talking about the 6.9 or the 7.3 diesel that Ford put into these trucks, no the pattern is different. I feel like ranting a little bit so here goes;
Why is the pattern different? Do you know what they did? The international diesel that they chose to install has some sort of oddball international pattern, not a SAE pattern. So Ford made a adapter to adapt the international pattern. A sane person wanting to save some money would think "if we have to make a adapter anyway, let's make one to fit the diesel to our 460 pattern". But no, Ford made a adapter, and made it to a one-only oddball pattern. So they had to re-tool their auto trannie castings to make cases just for the diesel, bellhousings for the 4 speeds, and had to get zf to make a special case for the 5 speed.
What was Ford thinking when they did this?

Joining and expanding on prior post rant:
Seems to be a Ford standard. Amazingly, the Coyote motor still uses the same pattern as the earlier mod motors. A Ford First!!!
http://en.wikipedia.org/wiki/List_of_Ford_bellhousing_patterns
Thousands of patterns....
Meanwhile, Chevy used the same pattern six, sb, bb..... One would think Ford would have taken notice of that at some point. Other than the SBF upgrade to 6 bolts from 5, is there some reason for the change--is there a substantial strength difference between these patterns an bolt locations?

And so again, as you note, the same rocket scientist thinking gets yet another bell pattern instead of using an existing pattern with the diesel and 460.
