Very reliable engine.
No special tricks to keep it going.
I would however replace the FIBER camshaft timing gear....
Mine just literally blew apart on my way home from work a few years ago, replaced it with aftermarket aluminum gear.
That is the only mechanical problem I've had with the 2.8, most of my problems with the 2.8 is the ignition/electical system, but that needs upgraded to the Duraspark conversion and the replacement of that rear solenoid regulator on the carb with a custom valve,you shouldbe good to go!
and that mysterious "10 tooth starter gear" mod, but I am nit-picking.
