I've decided to come into the twentyfirst century and I have a lot to learn.
So, please edify me.

 

In the late 20th century, they invented search engines (Yahoo, Lycos, Webcrawler, Google, etc), followed by Wikipedia....

 

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

 

im kinda late but here is some input. cross-bolted mains, aluminum cylinder head and aluminum block on dohc engine

 

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

 

Oh excuse me. It doesn't make it a modular but modular motors have those traits. Better??

 

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

 

Aluminum bluck only on dohc motor. Not always right but I got my info here. Modular Engines

 

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.

 

The number of valves and the material of the heads/block and what the engine was placed in has nothing to do with it being a Modular engine.

 

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?

 

AutoEngineLube Prelube System Reduces Engine Wear Up To 60%

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.

 

I thought modular meant that the maker had different components ready to bolt to the block. Do you want single or dual OHC? Do you want turbos? 2, 3, or 4v per cylinder heads? etc.

 

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.
