First thing I'd do is not refer to them by names such as magnum or powertech because they don't follow any logic to correspond to a certain year. There was a 5.2L magnum, a 5.9L magnum, a v6 magnum, and a 5.7L hemi magnum.

2007 and older 4.7L are all basically the same engine.
2008 and newer are all basically teh same engine(different from 2007 and older).

The architecture is basically the same with all 4.7's but in 2008 they changed cylinder head design, changed cam shaft profiles, changed the intake and exhaust manifolds, the throttle body, ignition system, etc.

Honestly, the 2008+ 4.7L has very little aftermarket support as well

Go to a hemi if you're going to swap.
