YES, they are defenitely cold blooded. When the temp drops to the zero and below area ( which is very seldom) the 4.6 in my Mark VIII turns into a completely different animal. Mine has an aluminum block and heads and it gets so cold it almost acts like it can't fire the fuel at that low of a temperature. It will try to fire and try and try but will not start. Then it gets flooded and you have to wait a while, charge the battery and try again and hope this time that it catches and runs. Don't touch the gas pedal. That makes it much worse. Just turn the key and let it try to start. I noticed this about ten years ago. When it got brutal cold Mark VIII may not start. Old F-350 with cast iron 460 fires right up. Mustang with cast iron 302 fires right up. All the old 302 powered vehicles we have fire right up (79 F-100, 87 thunderbird). It is a problem. If you have to count on it, I would get a block heater installed for the coolant. I always had something else to jump in to drive but I know what you mean. 4.6 dont like sub zero temps!
