GM guy needs info on Modular engines.

Hey guys and gals, I am a Pontiac and Chevy blue blood who is doing some research for my boss on what criteria Ford uses to designate an engine “Family“. I have done some internet research and I am getting mixed information. I am trying to research about the Modular engines “family“. Are the 4.6, 5.4 and 6.8 liter engines all part of the Modular Family or are each considered a “Family”? Do the 2 valve, 3 valve and 4 valves of each constitute separate families or are they just varients of the 4.6, 5.4 and 6.8engines? Or are the 2 V-8s considered a "family" with the 6.8 litre V-10 a separate "family"? Are the Ford truck versions of the 4.6, 5.4 and 6.8 engines considered a separate “family” of the Modular engines. What about the Modular engines built from 1994-2005 and the ones from 2005 to present, are they the same "family"?

What is Ford's official discription of an engine "family"?

The engines you listed are considered modulars. You have 2-3-4 valve, sohc,dohc versions. Same family.

The blocks on the 4.6l, 5.4l, and 6.8l are all basically the same. There is some slight difference in deck height for stroke difference. But they are the ford Modular Family.

The heads changed over the years from 2v, 2v PI, 3v, 4v, 4v Intech... And then theres the aluminum and steel block versions.

But the over all design of the engine is exacly the same. A lot of the parts interchage, but not all of them.

Triton is the pickup name for the ford mod motor. But its the same design as the mustang, cougar, crownvic, mark IV, Van. All use the mod motor.

Good luck

What is considered Modular engine family is those 4.6L 5.4L & 6.2L blocks means that the bell housing bolts are the same and so are timing covers (99.9% anyway) so accessory brackets from different RWD cars can bolt up if you wish to do an engine swap. Motor mount location are the same although you may have to interchange mount brackets. 2V and 4V heads can be interchanged, 3V heads will fit on the 2V/4V blocks but the pistons will need to be changed.

Thank You gents for clearing it up for me.

Even the new 5.0 is a part of the "Modular Engine" family. And all these engines share at least one thing, that being bore spacing so that they all can be machined on the same block machine setups.

The V10 is the best also.
