2004 ram 1500

Can someone tell me what is the difference the 4.7l v8 16v sohc engine compared to the 5.7l Hemi engine I'm looking for the performance and gas milage
difference on these 2 engines. Thinking of getting rid of my 2001 ram 1500 5.2 engine with 62k miles for a later year truck. I have noticed these 2 engines that are in the newer trucks.

thanks for the replys
