Hey Jim B,
John is correct, a D it is.
I got a 5 bearing ('28 cam) from you maybe year or two ago. You set it up for me (dual grind) to run a cast iron 4 port Riley on a D engine. Can't remember the numbers, but the head situation has been changed to a Serr 8 port, when it gets done.
So, the builder wants a billet so that he can make the HP that the D will easily handle. He said same thing as you...i.e.- can use 3 bearing. I said that that is silly when it is equipped with 5 ! Besides, if only three bearings are used, two bearings without oil holes have to be installed to BLOCK the existing oil holes in block. That would be wasteful, eh.
So, that's reason for original Q.
If I find a home for it, your 5 bearing product will go with Riley that you cut it for !
