It can have a larger intake because front end lift at high speed is not a concern for an off-road truck that won't approach 150 mph. Intake modifications can increase horsepower so I'm guessing it will get at least as much as the modern Hellcat engines, perhaps more as there is more room for airflow/cooling options in the engine bay of a truck. However . . . they could make all those modifications, then make other modifications specific to preparing the engine for truck duty and balance the power/torque curve more in favor of torque.
