Re: A #3932386 327 block
You must have misread that paragraph for the CRG site. The letter "I" was definately used in casting dates.
Here is the quote from the link you provided:
[ QUOTE ]
For cast-in date codes on GM-produced iron and aluminum castings (engine blocks, heads, intakes, water pumps, etc.), the letter "I" was used for September, and the last month of the calendar year (December) was the letter "L"
