Crane Cams - anyone used them?

Has anyone used crane cams in their cars?
My 2.7 has a crane cam I am told.
I have visited the web site and they only show 3 possible cams for 2 litre 3 litre and 3.2 litre.
I am guessing mine is this one as the performance takes off after 4K revs. Any other way of knowing from the outside?

here are the specs:
