I know Jon, downpour11, and at least one other person have WAY over 300K on their rigs.
If you're getting a little smoke, it's probably just your valve cover's leaking. Pretty easy and cheap fix.
With those miles, you'd probably be wise to do a complete tune-up, and look into getting an induction cleaning done by a Motor-Vac or one of the BG machines. Heard nothing but great results from everyone that has done it to a high mileage 3.4L.
