casting date to assembly gap

[Jason@JBR]

My 6618 DZ block has a casting date of March 31,1969. Assembly code is V0408DZ. Is that typical to have 8 or 9 days gap?

I do not like defining this as "typical".  Instead, this site would say "Normative Practice". Meaning, it falls into a range of being acceptable. Best to refer to the site's statement: "The block casting date must always be before the engine assembly date and it is usually very close to engine assembly date. Blocks have been found that have been cast and assembled in the same day, but that is not normative. There are also blocks that have been cast and then assembled months later; again, that is not normative. " found here,

Sounds "normative" to me.

There is nothing out of place with that spread.
