This is interesting! My 240Z HLS3002126 has a manufacted date of 3/70 and is registered as a 1970 model...in California. So I guess that equates to approximately 1300 to 1400 cars produced over a one month period or roughly 45 cars a day! Hmmmmmm, something smells fishy here regarding your registered model year.

The number of cars you are thinking were produced in a month is likely about right. In mid to late 1970 I have calculated that they were putting out about 2000 Z cars per month. This is just a rough guess since we only know the month of production and not the day (big difference between the 1st and 30th of the month). They seem to have really ramped up production after the first part of the year when they realized how popular the car was.

texasz,

It looks like we might need to compare notes in the near future as I have just inherited a 240Z with the a similar production date to yours: 08/70 HLS30-08323 (108 units apart!) and I was surprised when I lifted the hood to see a 1971 emissions sticker. I will post pics in a few days.

Now that is VERY interesting!!
