2013 Police 5.7 to 6.1/426 shortblock

I have an opportunity to get, cheap a complete sideswiped 2013 Charger police car with transmission, wiring, front belts, puppies and A/C, alternator as well as starter. In other words, everything. My intentions are to do either a Stroker 6.1, or 5.7 forgers internals, and use the cop car parts as donor pieces. I know that this has to have been discussed in detail before, but I can't find these posts. What I need ideas/suggestions on are will the parts work on the replacement short blocks, heads, intake, water pump, and front end pulley system, assembly? Then, about the wiring, I'll have the stock pedal assembly and computer with the wiring,can these be used? Or would it be best to just get one of the wiring kits out there? What can be done about using the VVT too? And eliminating the MDS. Any suggestions would help.
