85-88 are the same cam; 89-95 HO have the same specs, different part numbers have to do with things like material changes in the camshaft; gear hole being drilled deeper, etc. 93-95 Cobra all the same, and the same for the mid93 Cougar, Thunderbird and Australian Falcon.
There is a lot discrepancy from cam to cam however. Tmoss measure his and got .050" numbers of about 219/212 when most folks see numbers of around 210 duration at .050". Ford only specs the .006" durations, not the .050".
