LS2 vs LS1/LS6 Differences Here is what I have so far... I may be repeating some info from other threads a bit...
-Heads interchange
-LS2 has different pcm and harness
-LS2 has cam sensor in different location, cams will not interchange with LS1
-LS2 Water pump is supposed to be better
-Front drive accessories might not interchange due to sizing
-Crankshaft in LS2 has different reluctor wheel setup so will not work with LS1 pcm, but you can put a LS1 crank in a LS2 block
-LS2 intake will not take LS1 fuel rails, but will bolt to LS1 blocks
-LS2 family will eventually include all of the trucks
That is what I got so far after a week of checking around.

Curious about the camshafts. I had heard that some of the later production 6.0L blocks had oversized (on the OD) cam bearings, and that was going to be the standard for the LS2. The ID of the cam bearing would still be the same but the OD is about .050 larger than the standard LS1 cam bearing.
That is just what I heard from one of our block suppliers. No deffinite fact to that.
