There are some numbers missing. Some numbers are cast in the core, some are stamped after it's ground. Probably there is a 5 after the first 1 and 0? And maybe a couple more farther along? They are often above or below the line of cast numbers.
Moving this to the regular engine forum.
No, it`s only on the Shankle list of Alfa cams.
It is the stock 1600 Veloce cam from the 101 series cars. It received a "7" rating based on duration. You will find them weak at low and mid range RPMs.
That can be improved by changing the cams lobe centers to 104/104.
