DOHC tech shines in small displacement engines like you said. When you get into bigger displacements though it starts to become less and less of an advantage. That's why Ford went back to OHV with the 7.3l.The modular architecture - bore center dimension in particular - was probably about right for a 4.0L V8. What we got was already a mild 'stroker' up to essentially 'square' bore x stroke. Already a compromise.

The mod architecture was a compromised design from the start and Ford has done a pretty damn good job of pushing everything they can out of it. Arguably they pushed to far in some areas (plasma bore liners anyone?).
