    I'm working on a former NHRA C/SA & G/SA car with a small valve 455. The cam is a Kenne Bell MK C315. I would like to check the cam however I do not have the cam card and have not been able to find specs in any of my old KB catalogs.

    Does anyone have a card for this cam that they would be able to share?

    Sure it's not just a KB mark 3 cam ? Never heard of a KB mark C315 unless it's a one grind.

    Positive it is not a Mark 3. The lobes do not reflect sufficient lift. A local guy looked through an old KB catalog and it appears that the C-315 is also called an NHRA legal cheater cam however no specs are listed.

    I think your best bet is to have it cam doctored for specs if no response here. Did you try and get in touch with Jim Bill ?

    This is all I could find about it in my old catalog, seems like what you already learned:

    The specs on the cam look like they were secret never advertised you're gonna have to have the cam doctored.
