Help me identify these cams!

So I recently purchased these thinking they were BC 264's. I'm pretty sure I know the answer, but just want to confirm that these are really clean stock cams:

The cams:

The only markings. BC said their part number would be etched here, and on every other BC cam I've seen this flange is black, not polished:

Sorry friend how can we tell about the cam shaft without knowing in which engine it was implemented.

Did you measure the lobe (height, duration, etc)?? That is the only definitive way to tell the specs of the cam (which in turn gives you a much better idea of which cams they are) regardless of what numbers/markings are on them. With how many people have opinions and such, that will be your best bet (although you are probably banking on the fact someone else has seen/experienced these cams before).

Goodluck!
