The weight difference is the reason. Not the motor.
I beg to differ, as my other MK triton is the exact same model purchased the at the same time and has done similar kays but has been driven around by me for work, maybe I have a bit of a heavier right foot than some, while the lazy one was worn in by a worker who babied the vehicle and just put putted around and as a result it is way down on performance and doesn't look as if it is capable of recovering without a rebuild.
not all engines from the same factory line are created equal, and the way they are worn in makes an even bigger difference
