As an erk who worked on Vampire's & Venom's, this makes me cringe:

When they get this fat, no one tries to put them in the wing roots, like a Valiant or Comet.

That's a 737 engine being serviced by a midget.

The cowling ain't flat at the bottom! And it definitely ain't a MAX!

CF6 of some mark perchance. The Frogs seem to favour them.

The other thing to ponder is the diameter of that relative to a 737 fuselage.

The biggest turbine engine in the world, nearly as wide as a Boeing 737 fuselage, took to the skies for the first time on Wednesday, March 14 2018. The GE9X, destined to power the Boeing 777X, has a composite fan stretching 134 inches in diameter, more than 11 feet, tucked into a 14-and-a-half-foot nacelle. The engine is so big, it needs to be specially mounted on the wing to allow for enough ground clearance.

Though the GE9X is designed for the 777X, GE is flight testing the engine on a Boeing 747-400 flying testbed. Using an aircraft with four engines, only one GE9X, allows engineers to put the giant engine through the motions alongside engines with known performance envelopes (GE CF6-80C2s).

Where did I hear that before?

This time it's on a big flying test bed, not a passenger-carrying aircraft.

I liked the Lincoln testbed, or the Vulcan come to that. Bit trick sticking the new one on the nose of a 747
