fnt/rear diff gears should still be the same at 4.10.
same t-case.
20 HP is easy to make up with the 6.0 with a little cash..
most expensive to cheapest:
Turbo charger
exhaust
headers
maybe CAI
perf tuner
any combination of the above can get you nearly 20 hp if not more
lose whatever extra weight you dont need to lighten the vech will help.
use higher octane gas
better spark plugs and wires.
also for the tranny, i would recommend changing to the external tranny cooler if your doing alot of hauling.
im sure other people here have alot more input than me, and prolyl more accurate

Actually the 2008/2009 models have alot more than 20 more HP.....
The pre 2008 models had 325HP and 365ft/lbs. of torque, the 2008/2009 models have 393HP and 415ft/lbs. of torque.
Basically 70 more horsepower and 50 more ft/lbs. of torque.
We just came out of our 2006 into a 2008 a couple months back and there is really nothing we miss about the 2006 with the best improvement being in the interior.... the 2008 is noticably quicker and more powerful but at the end of the day the H2 is not some hot rod, its a big pig heavy A$$ truck that was not meant to be raced around so short of when Im towing the power isnt that big of a deal..... its just nice to have on tap when necessary.
