If you had a drawing of the lobe profile that you wanted and let's say it had a base circle of .327. Now you want to make a lobe with that same profile but with a base circle of .500. Take all the step dimensions from the known cam and multiply by 1.529 and that will give you the same profile but just a bigger cam lobe. Conversely, if you had a cam with a base circle of 1.062 you would multiply each dimension by .471 and that would give you a cam lobe with the same profile only with a base circle of .500. In both cases the shape of the lobe would be the same it would just be proportionally larger or smaller. I hope this is what you are asking.
