Is this an E303 Cam ?????????

[mr-xcr]

I just purchased what I thought was a used E303 cam.
Thats what I've been told anyway!!!!
Now that I recieved it in the mail I don't see the stampings on the end of the cam as other ford motorsport cams have.
The 6250 part # as well as the stamping of the E303.
What is on the end is the 3 slashes as the motorsport cam has as well as these numbers 1K20 as well as what looks to be E31 degrees . There is also a MT stamped on it as well as a P.
Can anyone make sense of this????
Please help if you can!!!!
Right now its useless to me so any help would be great!!!!
Thanks Guys!!!!!

used cam? I thought buying a used cam is a no no. Is it different with roller cams than flat tappet cams?

Buying roller cams is not always a good idea but if you have a good bit of knowledge and can tell that its messed up it would be obvious so its not to bad well the motorsport cams are all labeld on the back
