Re: drive train upgrades?
well interms of motor size going from 6.0 to a 6.2 liter is not going to be that big of a difference. Its the internals and heads that make up the new power. Im not sure if the DOD works on those or not. However with the extra torque and gears in the transmission you might actully get better mileage because you will not have the dead spot feeling at certain rpms...
