Re: V-8 head part nbr vs cast nbr

Packard did not always follow this practice but did it enough to use as a judge. The casting number is one digit less than the part number. The part number for the 56 head after machining is 6480407, the part number on the casting is 6480406. I have seen other examples of Packard using this procedure.
The forged crank made of unobtanium and found only in a dark pit in South Bend is 440989. I have strong feelings that the forged crank exists because Studebaker ordered replacement cranks from their supplier who made nothing but forged cranks. Here is mine with the part number stamped on it.https://packardinfo.com/xoops/html/modules/newbb/viewtopic.php?topic_id=205&viewmode=flat&order=ASC&type=&mode=0&start=140
