Pulled the cam out of a 350SB that was in a truck my buddy bought.Guy said it was a mild cam but who knows....Here's some info.

CMC stamped between the end lobes.
C40CP6 on the end of the cam.(not sure of the last C and the 6 may be a D- very lightly stamped).

1539 and 1.5 below it on the other end between 2 lobes.

Anyone know the brand or size of this bumpity stick?TIA-Joel
