1966 To 2016 engine & front end swap??

I have a 2010 Mustang GT that I recently bought. It’s gotta a lot of upgrades including a Roush cold air intake, Ford Racing intake manifold, a cam although I’m not sure exactly what kind, delete cats, and a lot of other things that I’m not sure about. It also has nitrous oxide hooked up the way it should be. The car only has one other owner besides me but because I got the car from a car lot I have no way of finding out exactly what all the first owner did to the car.
