Hope this helps.... Original (i assume) 3FE camshaft I have on the shelf. From measuring 4 lobes quickly with calipers, base circle is 32-32.2mm, major axis is 38.5mm, for 6.3-6.5mm (0.248-0.256") of lift at cam. I believe the rocker ratio is 1.5, for 0.372-0.384" of valve lift. The chart ERNRAM put together indicates 0.377" of valve lift.
These pics may help some with the modeling:
