So I have about 200K on my Ram (engine included) and it's been burning the mess out of oil since I got the truck at 150K and the other day my water pump went out and I changed it out and found out I also had blown my head gasket. I've been working on vehicles for some time now just not to familiar with the newerish dodges and not sure if I should try to rebuild this thing or put the 5.7 in it. And if so with the swap what all would I need. Any information would be great thanks.

 

If you search for "hemi swap" in this section, there are several threads regarding this swap. Here's one.
