plz don't discriminate my F-150
 

Mustang boards is the only site I could find that might provide some answers to my questions. So first things first, I do not drive a Mustang, I drive a 2013 F-150 4 door, but the engine is all mustang, my truck has the Rousch phase 2 supercharger kit on a 5.0. Right now I am producing 575 horsepower at the flywheel. Now I have a couple of questions.

1 will making the engine a stroker cause any problems with the supedcharger, ie cause damage?
2 will blue printing help the engine at all?
3 can my phase 2 be upgraded to phase 3 considering it is a truck.
4 lastly, assuming all of the above things were done, what would my gains be, and what would my mileage be? it isn't good to begin with.
