All new fluids and filters would be a good start!
Make sure your radiator is in good condition and not clogged up. No dried coolant hoses either. If you want to be thorough, a new water pump adds to peace of mind.
Then go through all the ignition parts from plugs to cap and rotor, making sure everything is in good condition and adjusted correct.
Suppose if you want to be extremely thorough you could put a new oil pump in there too, but if the car has been reasonably cared for with regular oil changes through its life, then that's probably a little overkill.
But in a nutshell, it's all about lubrication, cooling and ignition. Keep that in mind and your 4K should see you through just about anything...
