I am cooking for fathers day and need some help with my planning. I plan on cooking an 8 lb Butt, 6 racks of baby backs and would also like to cook a small Tri-tip(dad loves Tri-tip). I would like to get the butt done early Sunday morning and hold it in the house oven,then start the Ribs and Tri-tip which I anticipate taking 5 to 6 hrs. I guess my questions are can I hold the butt that long in the oven and if so what temp should I set the oven at. Also can I cook ribs along with the Tri-tip? Should the Tri-tip be above or below the ribs? Any help or suggestions would be greatly appreciated. I know it will all come out fine but haven't cooked for this many people yet so I'm trying to get my ducks in a row.
