I'm also working on a roller cam core design- - - - -two pieces of steel shaft material, spliced together with a machined-down piece of a stovebolt cam with the distributor drive gear on it. They will be heated and shrink-fitted to the center piece, then tapered pins will reinforce the coupling. The two blank areas will be machined for the maximum possible lift on the lobe locations and left completely round, to give the cam grinder people as much raw material as possible to work with. The size of the third bearing journal will establish the max diameter possible for the core lobes. Since the cylinder head design prevents high RPM performance, I'll be going for rapid valve opening and maximum lift, to enhance the low and midrange torque capabilities.
