Anyone remember the specs and part numbers for these cams. I used to have them written down, but I can't seem to find them anymore?

Where's Mike Yount when you need him?

The 93 Cobra cam is the same factory part number as a 93 Thunderbird 5.0 cam with 1.7 rockers instead of the 1.6 rockers the T-bird got. It's not a "special" cam.

85-88 - E5ZE-AA
89-90 - E8ZE-CA
91-94 - F1ZE-AA
95 - F4ZE-EA
Cobra - F3ZE-CA

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.

85-88 are 266/266 .444 lift w/1.6 (.278" lobe)

89-95 are 276/266 .444 lift w/1.6 (.278" lobe)

Cobra is 270/270 .479 lift w/1.7 (.282" lobe)

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".

Superman, I knew you'd save me. :nice:

Just curious....did all HO MN12's T-Birds/Cougars have the same cam grind, or were the pre-93's a standard HO cam?
