Hey Bubba, welcome to stangnet.
Yup, 5.0's from the factory started in 2011.
Why do you say yours is a 5.0? Has the engine been modified? Maybe a slight striker or bore kit has been added to it?
Like karthief was saying, look around the '05-'14 subforums. You'll get lots of help there from fellow S197 owners.
Glad you're with us.
