I suppose that since truck drivers don’t like to use higher RPMs to develop power anyway, that kind of makes OHC design’s greatest advantage less important. On the plus side it does make a much smaller engine — may fit nicely in E-Series.

Well that press release you linked to does say this:
Quote:
The 7.3-liter gas V8 engine delivers high performance in a compact package. Based on decades of commercial engine experience, this 7.3-liter is expected to be the most powerful gas V8 in its class – providing durability, ease of maintenance, and the towing and payload capability customers want. It uses an all-new cam-in-block, overhead valve architecture with cast iron block and forged steel crankshaft for maximum durability. Port injection with variable-valve timing optimizes the intake and exhaust to match performance with workloads. Oil jets cool the pistons under heavy loads.
