The oil pan I believe will be fine. The engine mounts also as long as they are for a hemi should be fine also. The main thing is going to be the throttle as the 4.7 uses a cable and the 5.7 is driveby wire so the TB is not the same. You may need to make an adapter to mount the 4.7 TB to the engine. The 4.7 pcm will run a hemi motor but you will need a tuner to adjust the fueling for the motor with the added cubes. The wiring will also need to be adjusted in certain areas as the sensors are in different spots 4.7-5.7

DakotaJ on here has done this swap already and likely has all the info you will really need
