Engine assembly date question

  • I know there are several experts out there who can clear this up for me;


    That EXACTLY does the engine assembly date mean...obviously thats the date the engine gets put together but how far is it built?


    1. Is it done only to the short block stage?

    2. Are the heads and intake put on at that point?


    In other words...How far is that motor assembled on that little stamped on date?

  • The whole motor put together with date code on deck surface is assembly day and shipped to plant for assembly with the car.There's a few days to two week or two months before final assembly of car down the line.Depending on the plant as to how soon the body and motor got together is factored in as to how many of each were built.Specific to Dearborn is really what I'm most familar with.
