I have a new GT with about 350 mi. on it. on start up i get smoke out have it for just a few secounds, i was told this was normal is there a problem with the 4.6s the car is still being broken in i have not even pushed it yet.

 

Your car is fine, smoke is normal at start up, its just the fuel that isnt completely burnt when the motor was turning over. I think you post in the wrong section though.

 

What color smoke? White smoke is most likely condensation, the weather is gettin colder..

 

I wouldn't say it's normal but I wouldn't worry yet.

 

Sounds fine to me, especially since it's getting colder out now and it's only for a few seconds.
