Your way better off the the older 4.9L. I worked for Cadi for 3 years and the 4.6 Northstar sucks. We were having to re-seal the bottom end of many of these cars, starting at around 30k miles. I think only one of our customers came close to 300k miles, maybe 275k when the head gaskets went. These engines run hotter then the older 4.9 and simply don't last as long in my opinion. However, you do give up a lot of power when going to the old 4.9L.
