Does anyone know the exact displacement of the Zetec engine? I have seen various #'s. My chilton's maual says 1999cc, Kragen.com and Carparts.com have their own figures, and when I entered the bore and stoke specs(from chiltons manual) into the equation for Displacement it gave me 1987.5cc. So what is it, I need to know! I have some very nice mods in the works

and I need precise data going into them. Thanks.
