Packard V8 states:Quote:
No indication that the 440912 crank was also forged??? If there is no documentation for a forged 440912 then it must be assumed to be cast (remeber DOCumeNtaion needed) ???? Therefore some doubt that PMCC tooling was actualy lost for the cranks????

We have a written statement from a Studebaker-Packard scholar stating the Packard V8 crankshaft casting patterns were destroyed when the Packard engine line was shut down. We do not as yet have internal S-P documents corroborating this.

All early crankshafts were cast steel. That 440989 is forged and superseded 440913 and 476009 is documented.

Since there is no information on the production method of crankshaft 440912, it would be impossible to state with any certainty of which method it was produced.

FWIW, detail on foundry operations from another S-P scholar:

Quote:
Wyman-Gordon began in the early 1900's as Ingalls-Shepard Forging. I worked there from 1975 to 1982, in Harvey, Illinois about 15 miles south of Chicago. Five other men from my family worked there also. My first year I worked in heat treating, a horrible job. After 14 months, a position opened up in the truck shop as a lift truck mechanic. I took the test and passed, so I transferred. Best job i ever had. W/G was so large it had five different unions, with five different contracts, so someone was always on strike. W/G built a big plant 100 miles south in Danville Illinois and busted the unions. This plant failed and a few years later they had a huge explosion at their Rome, TX plant. I believe the company subsequently went out of business. The huge steam hammers, which were so powerful they would bounce you off the floor when they struck, were dismantled and sent to South Smerica. Harvey, IL operations ceased around 1986.
