It does say that, but it's obviously in reference only to the T444E and 7.3 PSD. International also made the 6.9 and 7.3 IDI. If they only made 2 million V8 diesels that would mean, since they say 1.8 million are PSDs, that there were only 200K T444E, 6.9, and 7.3 IDI engines produced which would obviously be way off.
