after a bit of research i have made up a small list of factory displacement references for the ford i6. (EA to ED)

the main reason for posting this is (1) to check if the information is correct, and (2) if anyone wants to add to this list you are welcome and might include changes between the EF-BF. it would be helpfull. thanks
