LS1 = Modular engine?
something, as a house or piece of furniture, built or organized in self-contained units or sections.
a self-contained unit or item, as of furniture, that can be combined or interchanged with others like it to create different shapes or designs.
The head on the OHC motors contains all the goodies.
But as an adjective, it says - composed of standardized units or sections for easy construction or flexible arrangement
IMO, I'd consider the LSx/LQx motors more modular than the Ford motors. Pretty much everything can be exchanged on 4.8, 5.3, 5.7, 6.0, 6.2, all of them. On the Ford motors most parts can not be exchanged between the 4.6 and 5.4.

Modular refers to the factory they are made in because it is modular in that ford can switch its assembly lines around quickly to produce different versions of the modular family. Modular has NOTHING to do with the engine design

When you really only have 2 families of small block, and within the family they share damn near every part it really cuts down on selling new parts; and it's harder to say you have a new/bigger/better motor out there.
Seriously, though...Chevrolet does build good stuff, but think about how often they REALLY incorporate what the owners are requesting into the next generation of car.
Like stated above....
LSx's go from Cam Lobe--->lifter--->pushrod--->rocker arm (making a 180 degre turn)--->Valve spring/Valve. This is from the Cam physically being position in somewhat of the center of the engine. One camshaft sprocket/One Crankshaft sprocket.
"Modular Engines" (I will probably be corrected here) goes basically from the Cam Lobe--->Lifter--->Valve spring/Valve. This is from the two cams positioned on top of the Heads. Two Camshaft Sprockets/One Crankshaft sprocket.
*Disclaimer: I've never seen a "Modular Engine" torn apart, so I'm going of basic logics here...
