2014 hemi 5.7 replacing a 318 in a 1977 power wagon 4X4 ?

All I know is it came out of a 2014 Ram 1500 4X4 with 75 miles. It was pulled because the truck had roof damage during delivery. It has the vvt (not sure what that is) I'm guessing variable valve timing ? And I'm not sure what trans was in it. Can you tell what trans was in the truck by having the vin number ? I do have that information. I may have gotten in to deep with this modern technology ! I've read about getting the right flex plate to bolt up to the trans. but not familiar with the wiring. I was hoping some one had figured this out and was willing to share. Any advice is appreciated.
