The cost of upgrading is so high, it would be cheaper to buy a Longblock 09 motor then would be to upgrade a 06 motor. There is a significant number of internal differences between the two powerplants.

Not off the top of my head. However the Pistons are different the heads themselves are different all the valves are different and that's just the stuff that immediately comes to mind. Also the engine control unit is different because the redline is different.
