Anyone have an old cam dynamics catalog to help me?

Trying to identify a cam thats currently in my engine. The front is stamped 10309 or 10306 or 103096 or 103069?

The reason for the confusion on the stamping, is because a 6 is stamped over the 9 or the 9 is stamped over the 6. Thanks.

Thanks, I have the engine apart to fix some leaks. Car ran fine if I added Octane supreme 130, 1 qt to 10 gallons of 92 premiumn gas. wanted to see if I could get it to run better with no octane by checking the static and dynamic compression ratio.

Is this information from an old Dynamics catalog or from a current cranecams catalog? Thanks.

Cool! I actually found the specs in my 2005 Crane master catalog. I knew that they had bought CD a few years back and that they were single pattern grinds. I just wasn't sure about the #s because of the miss stamping. Good luck with the project

Just checked my static and dynamic and found them to be 9.7 and 7.6. Does that 7.7 seem a little low? Could that be the problem with 92 octane gas, so I have to bump it up with Supreme 130? thanks.

Sounds like the "new guy" held the stamp upside down when he ID'ed it! lol

Actually, I used that cam in a 468 BBC I built in about '95. It was a good cam, I really liked it.
