where to get gt motor
 

hey guys my 03 cobra is burning oil and is time for a new powerplant, so does anyone know where to get a 5.4 gt motor or crate motor? i know it wont be cheap, i dont even know if i can get one, but instead of dropping 30k + on a new 5.0, id rather have a sick cobra, thx guys also will my 5spd bolt up to the 5.4??
