don't quote me... but I don't even know what you own..
I assume a V6, since you had WP probs..
98/98.5 I think is 10:1
99/2000 is 10.1:1??? (to compensate for the slightly less displacement..)
The specific years the changeover happened MAY be off, but I would be more worried about the specific numbers I gave..
If you have a v6 Duratec/NON SVT I don't know what it is supposed to run..
Sorry I can't be more help.. there are TONS of people on here, and they will chime in, I am sure..
