No help on actually having hands on, but, I have often noted that just because it says "HO" or it is a branded spcical engine, the cam specs can be the same and the performance features are else where.
I remember from my Dakota days the 4.7 HO cams were different then the regular 4.7 cams. I think after a while all the 4.7s were the HO variety sort of like the 4.0 I6.
