Look at the comp cams website, 4062 may be a cam blank part number
I got a couple alphabet cams in the garage, I'll knock down some cob webs and see what number is on them
The 3355 and 3299 are lobe numbers. I'm guessing 113 is the Lobe Separation Angle. I agree, it may be a custom from Comp. You can search the Lobe numbers in the Lobe master catalog and find most of the info.
