any changes from stock configuration make it a higher performance engine which can be or not a good thing depending on the combination.
The 460s Ford put in RVs and F-350 isn't that different than a 460 in a LTD back in 1977. There ones that usually are much stronger are the HD engines like the 370-429 used in the F650s-F750s over the years.
460s Never came in these trucks from Ford.
I can advise you of a very good combination for you engine. (this was once my fulltime job doing this)
I worked at Crane Cams and my nickname there was Henry (because of my Ford knowledge) My real name is Jim
But there a few more things I need to know.
Does the RV have the Ford EFI or is it carbed?
I would assume it has a the 3 speed auto C6 Trans?
If you have a tach what RPM does the trans shift at @ WOT?
What is the Rear Gear ratio?
What is the weight?
Are you primarily at a high altitude(above 5,000 feet)?
What is your budget?
