That is, how many airliners have had their engines removed and replaced with engines from a different maker? The DC-8-60 to -70 conversions, the UPS 727s that went from JT8Ds to Tays, the 707/CFM56 prototype, and...? Any others come to mind? (We'll consider that bizjets aren't airliners.)

Didn't Atlas (Or was it Polar) have engine changes on some of their aircraft to make them fit into the rest of the fleet. These weren't upgrades, like the ones you mentionned, just type changes.
Cathay bought two of the test A330-300s from Airbus, and at least one of them had Rolls Royce engines installed where they were previously something else. Then there is 777 number 1 "Working Together" that had PW engines but now flies for Cathay with Rolls Royce engines.

Thanks-- I wasn't aware of any of those. So in addition to the original question, how about: what other airliners, if any, have changed enginemaker after having gone into service? Can anyone confirm the 747 freighters?

Thanks for that link, Southflite. So it seems that at least two 747s have converted from JT9D-7s to CF6-50. I wouldn't have thought it would be worth all the complication-- seems like it would be simpler to sell them if commonality was that important.
