I don't see why not.....it's just changing the cams

You just weren't able to order it from the factory I guess

You could add a Supercharger if you wanted...u know?? So it shouldn't matter at all....it's the engine & has nothing to do with the tranny
Go for it

 

Are you talking about the cams at the bottom of that link? They say they are designed for 1998 - 2004 4.7HO's... hrmmm will they still work?

Thanks sir.

 

They'll work

The 4.7 didn't change from 2004 to 2005......Still the same motor



And in that link......those cams are the ones that come in the 4.7 H.O. motor

So if you have a regular 4.7 and want more power, you'd want those
