I found the reply letter from Pat Cvengros regarding the cam journal size, of course this does NOT address the base circle of the lobes directly (as is the topic of this thread) , but if someone is getting a large base circle lobe on a stock core size camshaft in a vintage BBC I would sure like to know.
Here is the letter:

Tracy,
The camshaft may be of the large journal design; the bearings however must be a Babbitt type, non-roller design.
