LS2 vs LS1/LS6 Differences
-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.
That is just what I heard from one of our block suppliers. No deffinite fact to that.
