    When you say build if you mean machined and assyembled from the ground up i would definetly say no... start with a 6.0...If your just thinking about some bolt ons and even including a cam I say go for it.

    Intercolling is a must and I mean water to air or air to air. If no intercooler leave it on the shelf.
