Only thing that can replace a 3.9 V6 is the 5.2 or 5.9.
Only thing that can replace the 3.7 V6 is another 3.7 V6 unless you are electrically inclinded, then an 03/04/05 4.7 can be made to fit.
You may have the 3.9?, but 04 was the transition year I believe.

Probably not. The 4.7 changed considerably in 2002/2003/2004 time range depending on the build date of the truck. Easiest way to tell, one generation has 3 connectors on the PCM (passenger engine bay fenderwell) and the other generation has 4. They're not compatible.
