How many weeks?
« on: March 27, 2008, 12:40:35 AM »
Is it possible to have the engine build date the same week as the car and how many weeks prior to the build week of the car can the engine build date be?

There is much discussion on this topic elsewhere.

Short answer is yes, because the body tag date is not necessarily when the car was built. The body tag was date-stamped when Fisher Body produced it. Construction of the body assembly usually but not always immediately followed. Our business had a '67 Z/28 with an 06E body tag and a July 6th engine. This car was done in the early '90s before all the nonsense. Block was VIN-stamped and original; car came with protect-o-plate.

For the most part the engine pre-dates the tag [1-6 weeks] but there can be some big gaps especially involving low-volume engines. L72 '69 Camaros have big variation; 2 cars with the same tag date are known to have engine dates 6 weeks apart. Engines were not issued by build date either - an 02A Z/28 may have an earlier dated engine than an 01C Z/28. I have a db with over 600 69 Z/28 engine dates by VIN and while they do roughly flow over time there isn't much predictability.
