There were no torque specifications in that era, mechanics were trained to tighten by "feel". Though there are exceptions torque specifications really came into common useage as a result of WW II manufacturing.

However, respected publications like Motors Manual did give torque specs for later engines of the same type construction so you should feel comfortable using them for prior engines of the same design. For 1935/36 Eight and Super Eight, Motors recommendations are 67-70 for main bearing caps and 45-50 for rod bolts. The 35/36 rods would be insert bearings and the '34 rods were cast babbitt, so many would recommend more like 40-45 for the '34 rods with poured bearings.
