I would love to see an engine from the 70's go for 250,000 miles with nothing but basic maintenance (spark plugs, wires, cap/rotor, fluid and filter changes), and no oil consumption. Don't even think about pulling the valve covers either....
With that said, I am replacing the FI 460 in my '88 with a carb'ed 466 (C9 block, D0VE heads)

How do they fail before a mechanical engine?

I've replaced the damn thing twice (float valve and seat), but sometimes after shutting down she won't restart. Come to think of it, the JD did that too, just not as bad. Grrrrr... I hate ethanol blend fuel. Bad mileage, eats older fuel systems for lunch... yeah, REAL good idea there...

With that said, you won't find any '70's Ford around here on the original untouched motor after 150k miles. I've seen dozens. My buddy bleeds '70's Fords, and has owned nearly 100 over the years...he'll agree.
Either way...new motors will and do last longer...it's all the EPA emissions ***** that dies first...
