1 5/16 shell bearings

I too was waiting for an expert response to this one, but I think shells would not perform as well as white metal in a splash fed engine, where the flow of oil through the big end, which means it has to get in and out easily, would be less. Be interesting to know why you want shells, and what benefit you expect from them. Pressure fed engines are a different world beyond my ken.
