Interesting. I have read similar articles saying much the same. In fact that Honda quote is in the book I bought about building Mopar engines for performance. The book details everything from the crankshaft up to the intake on how to build a good performing Mopar small block engine.

When all is said, engines come down to breathing. Comparable engines like the 5.2 and 5.9 breathe similarly up to some point, and then one is better than the other. Comment made above how the 4.7 is not as good as a 5.2 because of the overhead cam design. When actually, had Chrysler developed the breathing of the 4.7 heads like was done for the 5.2/5.9, it may have developed the power possible in the block. The 4.7 is a stout, solid block design from the crank up, with some oiling and cooling issues that Chrysler eventually addressed. But perhaps the valve train architecture/head porting of the 5.2/5.9 can't be as easily designed into an overhead cam head, to capture the breathing capabilites of the Magnums. Honda knows how to make an overhead cam engine make power.

Eventually it comes down to packaging. Ford made the SOHC engine, a really good looking engine, but had some issues with cam chains as it was developed for drag racing since NASCAR was not going to allow a "non stock" engine on the big tracks: https://www.motortrend.com/news/90-day-wonder-sohc-427-cammer/

Had Chrysler learned from Ford, perhaps a stronger 4.7 OHC could have been developed. But the success and legend of the Hemi far out shown the possible Chrysler Cammer engine.
