Actually it was Air Astana that took the last delivery in June 2014.

No, Boeing is only selling the 77L, 77F, and the 77W. They all use the same engine just with different thrust levels, firmware, and maintenance schedules. The 772 and 77E engines are no longer being manufactured by PW, RR, and GE.

There was a huge engine change in the late 1980s when the 767-300ER came out. The marketing teams didn’t make as big of a deal as Airbus/Boeing do nowadays, but that was a big engine upgrade and 50% range increase.
If you compare the CF6-80C2 to the original CF6-80A, the changes are similar to what the CFM56 to LeapX in scope. Similar with the JT9D to PW4000. 20% increase in thrust, larger fan diameter, higher pressure ratio, higher bypass ratio, etc.

I wonder if United could potentially hunt for newer build 767s owned by other airlines to replace it’s older frames.

I'm not sure if they're already flying for United or are still being checked out, repainted, etc., but the point is United is actively looking for more 767-style lift and acquiring it when able for the right price.

UAL has agreed to take 3 HA 763s. Time will tell if they find more and how many will be replacement or growth aircraft.

Wow - I had always assumed it was more like going from a CFM56-5A to a -5B

The 767 was designed from the start as a twin engined wide bodied jet that used the same engines as the 4 engined 747. It cut down the development costs. It also made it possible to operate fleets of 767's and 747's with one pool of common spare engines. The 767-300ER benefitted from the improvements in engines developed for the 747-400. The improved efficiency of the engines supplied by all three manufacturers for the 747-400 allowed the 747-400 to have the same range as the 747SP but at a much lower CASM. The same engines installed on the 767-300ER allowed for greater range and payload while extending extending the number of routes that could be served by twin engined wide bodies.
UA even used the same ETOPS protocols for maintaining the engines for their 747-400 fleet as for their 767-300ER's even though that was not required. It supposedly cut down the cost of spares by not having to have duplicate spare engines available and by increasing the dispatch reliability of the 747 fleet. A 747 is twice as likely to have an engine failure as a 767 if the engines are maintained to the same standard. They are more than twice as likely to have a shut down if normal 747 standards of maintenance are used. As neither a 767 nor a 747 may take off in revenue service with an inoperable engine, using a ETOPS maintenance increased the dispatch reliability of the UA 747 fleet.

The new engines come with some disadvantages. They are a lot heavier (heavier materials allow for higher temperatures and pressures thus more efficiency) and costlier (manufacturers know the new engines are reducing fuel costs and they want a piece of the action!). Overall a win, but still one needs to consider all the variables.

Can someone explain the points in bold? If the engines are maintained to a higher spec, applicable to both aircraft types, why would the engines on the 747 have potentially higher failure rates?

I guess the question could also apply the p-8 Poseidon (military 738) with raked wingtips versus the common style 737 blended winglets, and the 744 winglets vs 748 raked style.

The winglets came through a rather unique third party after market option that then got partnered and partially absorbed by Boeing. Boeing was not particularly supportive of Aviation Partners who developed the blended winglets. Boeing didn’t offer a raked wingtip retrofit, but Aviation Partners offered a blended winglet based on some of their prior designs that offered measureable savings. Eventually Boeing partnered with them which is why we began seeming blended wingtips in production on 737 instead of exclusively through retrofit.

The 767 passenger variants stopped selling in the late 90s because they no longer had compelling payload and range offering once the A330-200 entered service. Product configuration - and not system design - is consistently the dominant factor that leads to a market leader or market loser.

Yes, for some reason they kept things quiet. If anything of the magnitude (PW JT9D vs PW4000) was done today, the type would probably get a new name and new house livery!

Exactly! Airbus added the suffix LR to the A321 for a 3% MTOW boost of only 7,000lbs. The 767-300ER was a 13% increase in MTOW which added 45,000lbs and increased range about 70%. I think marketing would have scoffed at calling it the 767MAX back in the 1980s.

I guess it was different times back then.
One thought is they didn't make a big fuss because the engines were literally the same ones that were already made available for 744.
We see these days GEnx for 787 and 748 are not interchangeable like 767 and 744 engines were:

A bit more than that: they have different fan diameters and the smaller/lighter -2B 747 motor also drops one LPC and one HPC stage.

The 748 doesn't need as much thrust per engine as the 787.

If Revelation knew about the fan diameter and stage reductions, don't you think he also knew the 747 engine has less thrust? Give the man some credit.
