This pertains to the earlier reference to the forged crankshaft found in my Carib. I thought I would post it here as well. Information is from the Studebaker Service bulletins.

I finally found the text for which I was searching: RE: 440989 and 440912
PACKARD REPLACEMENT CRANKSHAFTS - 5580 AND ALL 1956 MODELS
Crankshaft part No. 440989 is supplied as a service replacement, for the 5560-80 and 1956 models, and supersedes Part No. 476009. Part No. 440989 is a drop-forged shaft and does not have the large openings or holes through the connecting rod throws. All oil passages and lubrication openings remain unchanged.
In some cases, due to a stack up of tolerances, interference at the rear counterweight and cylinder block may be encountered. When this experienced a portable grinder may be used to grind off sufficient stock from the CYLINDER BLOCK to provide a safe amount of clearance for the counterweight.
CAUTION: NEVER remove or grind any stock from the crankshaft.
Part No. 440912 is available as a service replacement for models 5522, 5542, and 5547
Part No. 440912 replaces Part No. 440594
