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