Camshaft dimensions curious Do you have orig mfg specs?

what are as manufactured dimension/specs for the 5/16 and 3/8 camshafts?
I’d like to know the dimensions of back of cam to lobe top, the circumference of round part (off lobe…side to side)…and what are the duration specs etc. I have measured with caliper (on 5/16) but want to verify against factory mfg spec. Anyone have it? ( in selecting a replacement cam it will be wise to check).Cams changed a bit over the years…interested in all the iterations that could be used in an XK.Thanks Nick
