58 dodge d100 315 poly

northern 313 is a bastard for parts , tried to get some info on another project with one of those . couldn't get much info , but the bolt pattern on the rear of the block for a bell housing mount should be the same as all early blocks 241 259 270 291 301 315 318 325 330 331 345 392 . but i'll not sure of the alinement dowels . all of the american blocks use the same pattern for them . so there are adapters out there for gm or chrysler trannies
