I have a 95 with 207K on the engine. Long Trip. Car question.?

I have a 95 Thunderbird V8 4.6L engine with roughly 206K Miles on the OD. I have done these things myself and though service stations: Replaced ball joints, brake pads and rotors, Serpentine Belt, Oil changes every 2000 miles, K and N intake (Short Ram), Brake flush, Radiator flush, Fuel line flush, alternator, and a transmission rebuild all within a year. I recently also refitted the PVC valve tubing's that had been cracked. I am taking the car from FT Lewis, WA, to Buffalo, NY this summer and plan to drive strait through. How do you think the Engine will fair? It seems to be going strong but will eat a quart or so of oil every other week. No major leaks I am aware of. Is there anything I should be wary of in the meantime? Any other PM I can do to ensure it wont cr*p out on me? I think the car just has a lot of highway miles on it and was fairly well maintained. I've had it since 198K. Thanks for any insight!
