Re: engine identification
according to my most used ford parts decoder i got this;
4-4 = 1984 year
a - generic ford/ galaxy/ full sized ford.
6000-6898 = Engine
FA18 = to the best of my knowledge is the revision number. usually its only a digit or two, but this one is 4 so I'm not one hundred percent sure. it would be one heck of a revision number as it is usually a-z, then a-z in double digits.
