i know it is the same as a mustang engine but what is the ratings of these engines. i think it has the same cam as the 93 cobra or some kind of cobra. it is MAF too. not sure if the pistons are hyper or forged. the intake plaque said 5.0 HO on it but i don't have it anymore, since the screw was stripped i had to break it off to get to the intake bolts. it is the roller cam and it was very fast for a tbird. i have an 87 gt motor to for sell and i am asking if this motor is the same as the 87. i know it should be but i the could be buyer is not too sure of it. i just know more about this motor than the 87 one since i did not ever drive the 87 engine.
 
I don't know the answers to all your questions, but I do know that they didn't phase the Cobra cam into the t-bird 5.0's until 93, so the 91 does not have the Cobra cam. According to the cam data I've got, in 91, the T'bird had the same cam as the HO Stang - .444" lift, 276/266 advertised duration.
