shoot trix and process in hc-110 or Rodinal and make 16x20s. That ought to give you grain. Maybe process the trix in Dektol and I know that will give you grain clumps. You could shoot it (trix) at 1200 and process in D76 straight. Make 16x20s. That is how I remember film being shot in the 1960's or 1970's. YMMV.
