I posted in the wrong forum before, so I am moving to this indstead. I wonder if anyone knows what these cams are? They are still in the box and wrapped with protective oily paper. They are for the Alfa Nord eninges. 105 and 116 Alfas. The box says:

AR131292C 41 degrees, 71 degrees

but I don't now anything about them. Any help is appreciated.

Well, most likely Alfa Romeo, 13.1mm lift, 292 degrees duration. That's a pretty serious cam.
I'd guess C&B, from the numbering convention.

Aha, I have three different pairs, as below

AR131292C 41 degrees, 71 degrees
AR114308C 52 degrees, 76 degrees
AR131282S 33 degrees, 69 degrees


in the original unopened boxes. Wonder what to do with them. :mellow:

Test each one and see how they are! With lifts like that, you'll be doing a lot of tappet bore relieving. And needing high revs to work with that overlap.

I'd think they'd have a ready market of real or boy racers.
