Turning down stroker crank

turn down the mains for the 400 block no problem, many times that been done, with a steel crank and no rehardening-ok cuz a layer of oil when running. I would forget about the chevy rods-they are narrower and you do not need to offset grind for more stroke, or does anyone make steel rods with the smaller big end in the mopar width? years ago we got some aluminum rods someone was making in limited batches
