I have a custom Cam Motion Roller for a SBM, the numbers stamped into the end of the cam are 699356 and 94g1c. On the cam card for this cam the grind number is R2606-2681-06. Cams specs are
Cam advance/retard is +4 degrees
Lobe separation is 106.1 deg.
Lobe Center is 102.1 deg.
Duration @ 0.050 is 263.3 deg. intake / 270.2 deg. exhaust
Lobe lift (1.5 rocker) is .64152 inch intake / .62882 inch exhaust
So the 699356 number is the only number on the cam card. So I think that number designates a Small Block Mopar LA cam.
The other number 94g1c is not on the cam card. So I think that is a number that the cam grinder uses to identify the cam, but not sure.
