THe Sept 56 price list does indicate 440912 (ENDING IN TWO) and 476009 cranks ONLY. NO others.

I wonder if the Studebaker National Museum has the blue prints on these?
Would be interesting to see what notes, or changes are mentioned on the blueprints.

I suspect that they might very well, but it's beyond my present means to pursue that research.

"So, it's still my gut feeling that the forged cranks were produced well before 1959, but for some other purpose, and that they were simply made available, later, as service replacements for these cars when the supply of original cast cranks was exhausted." Yes. Based on the standard MO of the auto industry, especialy of that era, BH's gut feeling is the most likely and probable. Note that the Studebaker historian in the one of the above quotes indicated that such items as heads and blocks were NLA at that time but that cranks WERE AVAIABLE???? THerefore it is most likely that subject cranks (forged) could have been left overs from some earlier production run. OR to put it another way: If Studebaker didn't bother to produce heads and blocks for service replacement ca. 1959 then why would they have bothered with cranks???? The only reasonable conjecture is that of BH's claim as quoted above.

From BH's post #43 above:
"..which can be summarized in two lines of suppersession: 440594 => 440912 440913 => 476009 => 440989" Something peculiar there. I do not claim to be somekind of supply chain professional nor expert. BH is the only current member to fit that bill. But is it not peculiar that a supersesion (440912) would be ONLY ONE DIGIT off from a PREVIOUS number superceded (440913)????

From post #35 above:
"For some reason, the manual transmission bellhousing pattern seems to have survived as there are some with later casting date" So were such bellhousings used in Marine or some other non-passenger car applications???? Mite thus explain the forged cranks.

At this point, pending any EMPIRICAL contradistions, i beleive that ANY Packard V8 crank is I'changelable with ANY OTHER packard V8 crank. The only diferences mite be in metelurgical strength or some other structural part of the crank that would present no problem with fitting the crank nor its service capacity except maybe under very extreme service demand. . Balancing irrelevant.

Bh's post #43 above needs to be book marked, or PostIt noted or what method is used to keep it easily accessed,searched for, or referenced for the future.
