Here's a good "Modular Engine 101" link: Ford Modular engine - Wikipedia, the free encyclopedia

A engine being a DOHC does nothing in making it a modular engine nor having an aluminum block

Not necessarily. There are some iron blocked 4V's, as well as some aluminum blocked 2V's.

That article was written before Ford used a 4V iron block and a 2V aluminum block. The '03-'04 Cobra received a iron block 4V, the '01-'04 Explorer received a aluminum block 2V, and the 3V Mustang blocks were aluminum as well.

Mod motors are called modular for their manufacturing process. The bore and machining is as streamlined as can be for making 3 different motors off the same design. the triton V10 is simply a 5.4/4.6 (stroke length escapes me ATM) with an extra cylinder to each side. That help?

has nothing to do with the engine.....engines are plain jane legacy motors....modular refers to the tooling used on the assmbely line machines that assemble the engines. the assembly line machines hare quick change "modular" to provide tooling for vaarious engine types.
so the next time you hear "todays modular engines are this and that" , not true, the engines themselves are the same legacy short blocks being produced the last few decades.

The modular engines all use the same tooling to machine them, decreasing downtime when assembling the different engines. It is simply a matter of the manufacturing process. But if you're looking for some sort of similarity between all of the mod motors, all of Ford's modular motors have a bore spacing of 100mm.

common belief.....modular is all about the tooling process...the equipment used to build the engines have modular componets....there is nothing modular on the engine themselves across the whole engine family.
