Quote: I have a matching numbers car that the build date was the last date of the mod year...block was cast 1-1 of the same year, whats that 7-8 month gap???? Why??
One possibility is that there was a problem with the casting; not enough to scrap it but enough to delay machining/assembly.
There have been multiple examples posted on this forum of wide gaps between casting dates and build dates....proof that "there ain't no rules" when discussing dates.
