Parts number wise I see the following...
From here.
In mid '07, Eric Brooks states that '03-'04 Cobra cams are the same as the GT500 cams (we can assume he was looking at '07 GT500 specs for sake of argument and I think we can all agree they were the same at least through '09, yes?).
From here.
One week ago, in the same thread as above, Michael at L&M states
From here.
Michael makes no distinction between '07-'09 or '10-'12 cames being any different or any inference that late GT500 cams spec the same as the old GT cams.
You mentioned Tousley, and I found a thread where they stated
While the cams from FRPP are no longer available, the FRPP page linked states...
From here.
If the GT cams were the '10 and later GT500 cams, that would mean that the lift on each cam was over 1mm more (can anyone find the OE specs for a '10 or later GT500?).
I guess the bottom line is this...if they were the same, anyone looking for a set of the now unavailable GT cams could just order from the Ford dealer a set of '12 GT500 cams (for example). Because the inference here is that they are the same, right? Then why is MMR out of them and fairly recently at that?
Check this thread out to see what I mean.
I am just repeating what Steve told me and I cant remember what year GT-500 he looked up, he was surprised as was I. I have owned two sets of cams and still own one set of FGT cams so I should be able to confirm what Im saying shortly(dont have the cams on hand).
Also those part numbers are NOT what I recall being on the cams.
I can only remember part of it. Im not sure if I have left and right correct.
-270 Right Intake
-271 Left Intake
-272 Right Exhaust
-273 Left Exhaust
Those numbers are what are on the cams not what Fords part # says.
Here is what I got from the physical cams themselves. Excuse the hand writing.
It would have to be the 10 & up cars or when the horsepower rating went up between models. I cant remember which year exactly. Also that is how I found out. It was the only other cam option I could think of besides stock 03-04 Cobra cams. You can order them for 220 a cam or 880 a set from Steve at Tousley.
