Wow 445 horsepower and 910 pound-feet of torque that is quite the increase over its old power ratings. Interestingly it seems like they went with the same displacement that they previously had. I wonder what modifications they had to make to the engine in order to achieve this power level because they last stated that they stretch the rubber band pretty tight.
I don't think much on the engine, maybe stronger rods. My 09 has been at 530 hp and 1050 +- foot pounds of torque for over three years now on tuning alone. They will need to beef up the Allison 1000 though.
