My guess is the main differences between the '01 and '14 engine won't be the engine block itself as much as all the associated engine "doodads", such as the differences between the '88 and '93. Definitely want to use all the '01 wiring, and if you have a full set of the '01 doodads (little valves, sensors etc, maybe manifolds and other plumbing) to put on the '14 block seems you should be good to go...
In addition to the '14 service manual online parts fiches for the two years are likely to be a good resource to tell if any particular gizmo that looks the same between years actually isn't...
Ought to be an interesting project...
