I'd say it depends on the engine. A newer 5.4L or 6.8L should have better durability/fewer leaks/etc than a 5.8L(351)
Either way, expect minimum 200k on a gas and 300k on a diesel. Expect a rebuild 5.8L to be cheaper than an 5.4L or a 6.8L
Lastly, I personally would avoid a Ford 6.0L diesel. Dmax is a much better engine. I know that is a point of controversy, but 6.0L problems are well documented
