My E-450 I has the 4:10 rear end and 6 speed trans. At 65mph the engine is turning about 2300 rpm. The engine stays in the powerband in 6th gear at highway speeds so there is no downshifting for overpasses and bridges unless they have very steep inclines.
I forgot the de-tuned 7.3s still get the old 6 speed trans (5th and 6th basically like 8th and 9th in the 10 speed).
It's a decent pairing since the 7.3 has power for days.
If the OP's little van has 4.10s as well, I can see how he thinks it's getting high rpms at highway speeds though. But it should pull like a train!
