I had remembered that as a cataloged cam from UD, but I looked in my old catalog and it’s not there.

Then I remembered the two that I used were just something I had ground.
Only 3 lobes in that lobe family, 296, 308, 312.
The 312 is listed as 280@.050, but since they didn’t use different(bigger OD) masters for the BBM core size, it would grow 2* @.050 from the design spec.

Listed as 312@.020, 280@.050, 201@.200, .4567 lobe lift.

I had really good results with those.

The 311R8 was also quite popular.
Very similar, but slower lobes.
