This cam came out of a rebuilt 340 . The only numbers/letters on it are - (CCS 644) . Numbers/letters are on the back side of the cam . We thought it was a Comp Cams , so we called . They said there would be some more numbers on it but , , there isn't . To that while still on the phone , Comp says it's not there's ? ? So , if anyone recognizes these numbers send us a message . Thanks and Merry Christmas . . .
