Someone can correct me if im wrong but I think that you are talking about the 4.6/5.4 modular engines...I believe that it is reffering to the engine being Overhead cam engines instead of pushrod. Im not entirely sure on that one though.

"Modular" refers to the interchangeability in the basic engine design...that's the best way I can put it.
The 4.6 in both 2 valve and 4 valve versions are the same bare block and if I remember right, the 5.4L is the same basic block with a different crank and heads (among other tweaks) for the extra displacement. The pressed in cam lobes that the 5.4L gets over the 4.6's (at least initially) were something that raised my eyebrows a bit...in a "That's neat" sorta' way.
The v10 is just the 5.4L with the extra cylinder on each bank piled on. The v10 can use a lot of the 5.4L parts that are not related to the length of the engine (cam, crank, etc) like radiator, tranny, accessories (Uh oh, some v10 swaps in the works, I bet!)
The Windsors weren't that way. While the 302 used a bit of the 351's parts, they were NOT the same block. The 460 wasn't related to the small blocks either.

it allows ford to use parts from 1 basic design to build many motors by just adding on. shareing of parts reduces costs of building each motor. a 5.4 and a 6.8 share bores and strokes and can use the same pistons and con rods. bearings, rings, valves and some gaskets .https://www.fleet.ford.com/truckbbas...005/specs.html take a look here and you can see what can share what

truth is i don't know. the stroke is longer on the 5.4 and 6.8 then the 4.6 so you may be correct. they all have the same bore . maybe shorter rods to make up for the longer stroke. piston pin location? the stroke is 15.6 mm longer has to be some where. any one know the fact?

The 5.4 has a taller deck height than the 4.6. Think of it like the 351/302.
It is absolutely correct that the V10 is the 5.4 plus an extra cylinder on each bank.

The 5.4 is essentially like a stroked version of the 4.6l
It has exactly the same bore, with the addition of - a slightly obscene - 4.17" stroke.
The heads between a 4.6 and a 5.4 are interchangable (yes you could put 4V heads off a 4.6 Cobra onto your 2V 5.4l F250 if you felt the urge - thats how they created the Cobra R, and our 4V 5.4 Falcon engines BTW)
The 5.4 (and the V10 for that matter) have a HUGE block - check my gallery for the size of a DOHC 5.4...

if you get that much out of a 5.4 what could come out of a 6.8, 680? i would love to see ford do a 4 cam 4 valve variable cam timing 10.0 to 1 6.8 v10 together just to see what it can do
