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"?
