I stumbled across this article this morning; it does a great job showing and explaining the differences between the 5.7 from 2003-2008 and the 2009-present Eagle 5.7. It does a good job getting into the details of what changes were necessary to accommodate VVT and MDS, etc...
Some notable differences include:
-Connecting rods
-Crank
-Cams
-Heads (obviously)
-Valves
-Blocks
-Intake/Exhaust ports
-Pushrods and lifters
There's also a lot of good info on the differences in timing systems.
I thought about putting this in the powertrain section, but then it could go in the one for 3rd or 4th gens, so I figured GD would be a good central location to avoid a duplicate thread.
