Ford's SVT Enthusiast magazine stated that the 2000 SVT had reduced the displacement to meet European standards. The same article says that the compression was raised from 10:1 to 10.25:1 to retain the 200 horsepower rating.
I have not seen any other publications about the change in displacement.
So the change in displacement was for the model year 2000 according to Ford. Does anyone have any evidence to the contrary?
