5417 # used by Alfa Ricambi (USA) for the old Shankle 7L cam 10.7mm lift, 102 degree centers, .006 clearence intake, .008 exhaust, HD valve springs recommended.
I post before i leave for work and i come home this morning to find the answer and more!! Thank you very much for the info.

Best for a 2L? Seems a bit hot for my 1600.

Cam application

If it is a 5417 the Duration is 237 deg. @ .050 cam lift with .006 clearance.
The 1300 & 1600 Veloce cams were 245 degrees, so your gain is from 1.5mm additional lift. Should be good cam for the smaller motors as the shorter duration/higher lift should improve lower end torque (less overlap) as well as improving overall performance due to upper profile duration increase & lift where fuel air mix is flowing greater.
The cam would be an excellent exhaust cam in a 2 liter with intake cam of larger duration & lift.;)

Same thing. I found another set of cams in another Alfetta head, no markings except a 309 on the very back of the cams. Cams look almost identical as the ones pictured above, except for the 309 mark in the back. Anyone have an idea of what I'm holding?

So i found two sets of cams:
First one says "309" on the back and has four tool marks . It has about 11mm from base of cam to top of lobe, so im guessing its a 10mm?

The second set says "306" on the back with three tool marks. I got the same measurement on it as the first, lobes look similar, but then again i don't know much about the subtle differences in cams.

Anyone know the specs on these?

Cams

Thats not the way to measure lift!
To ID it helps to have the base circle measurement. When you record that, set the calipers to "zero" then measure total height of the lobe from the bottom of the lobe to the top.
From the #s they are old Shankle / Alfa Ricambi stuff. Most of the cheap cams for providers was (and is) done by Delta Cams or Megacycle. They should be able to profile from the grind number.

Get the BC & lift & post it & maybe it can be identified...
