I.d. this bog block 727

Hi I recently got this 727 trans with a 440 I bought does have torque converter. Just trying to figure out what year it is. Was told it's rebuilt so other question can I take the new internals out minus the valve body and put in a later date 727 core im needing a mechanical linkage shift trans for my 72 dart. Numbers on side are G2466147. 2181327 btw the engine does not match trans as its a 77 440 truck engine
