I have a set of camshafts that came with my Duetto. They have these numbers on them 10 03 2000. I was told that they were performance cams. Does anyone recognize the numbers?

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.

Shankle lists 101210320000 - 1600 Veloce; 9.5mm lift, performance rank 7
and
101000320000 - 1300 Normale; 8.6mm lift, performance rank 1

Those are the closest numbers in the catalog to the one that you posted.

Cams

Look at the #s closer. The stock cams are 10502 3200 01 the #s are not all "cast" they are cast and stamped.
Lift is 9.5 Rank 5.
Not performance cams.

thank you all

I see the stamped numbers, with them it is 101210320000. It is the Shankle.

Cam

It is the Shankle.

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.
