block cast date vs car assembly date.
Just wondering what the general opinion is on this for a 69. if a block cast about 4 months before the cars assembly date is most likely a replacement block or could it be original? I know NCRS says 6 months but that would be rare. And it's been decked so the stamped numbers are gone. Thanks for your opinions.

The stamped numbers possibly could be raised with Acid. Not NCRS of course, but could answer your question.
Yes it very well could be original at 4 months in my humble opinion.

Hello,
The transmission case was typically stamped with the VIN at the same time as the engine using the same gang holder.
It would be interesting to know what that stamp looks like.
If the price of the car reflects the decked engine block it's not a big deal.

My early August 69 build 1969 block has an April cast date and late July build date. Additionally I have a few other dates parts in April. I bought the car off the original owner. Nothing was replaced.
How does the engine “assembly” date jive with your trim tag?
Keep in mind there was a strike in the spring of 69 so some parts, date-wise) can be stretched a bit.

...I know of an original '71 that had a block date 8 to 9 month's out that was original to the car. That same car was looked at by a few prominent NCRS/Bloomington judges that said it was absolutely original to the car when it went for Survivor. It was a Dec 7th built 1971 and the block was cast March or April of 1970 that I recall.

...remember 1970 was a shortened model year and also a strike year, so that does throw a wrench into things. That "6 month rule" is widely accepted, but it's not gospel either. There's always exceptions to the rule.
