Engine parts date codes.

From what I understand from the website is that date codes for engine parts can vary up to 3 months??? What I'm asking is, was this something that GM was very strict about? Were they just pulling engine parts out of bins and assembling them with whatever they had?? In the case of my car which is built in 01B Jan 1970, all of my parts are dated between the 3rd and 29th of Dec 1969. Exhaust manifolds are the only parts I don't have at the moment, so is the value of the car going to suffer if I install Oct or Nov 1969 manifolds?? Or were all engines built with the same month dated parts?

Re: Engine parts date codes.

You have it correct. Whatever parts were available at the time is what went on that car or engine.

Re: Engine parts date codes.

I've seen legitimate cars with 6 month span on some parts dates. I had a legit '69 Z28 that was built in May, and the engine was cast in January. engine not assembled until late April.

Authentication and pre-purchase inspection service still available. PM me for more information.
