I have a 96 T-bird with the 4.6 2v and i am wanting to make it go fast, really fast to be exact.  I was wanting to know if it would be possible to convert the SOHC over to the 96 cobra's DOHC heads and intake.  If it is possible, what all would i have to do.  I can get the whole engine pretty cheap (haha) from a friend of mine and possibly the trans.  Any info would help alot.  

Getting a complete engine would be the best way to do it, especially if you can get the accessories with it.
