exhaust manifold date codes

    I have a pair of K manifolds which have date codes of K24 and K54. Can anyone tell me how these read? K=Oct, 2=day, 4=year? Thanks, folks.

    It seems you have already figured out how to correctly decode the dates on those manifolds. <img src=images/icon_smile_wink.gif border=0 align=middle>

    Checked mine, (April 65 dearborn car) and they are simply stamped G2 on each manifold, along with the engineering numbers. This information may muddy the water a little. Will provide an image to you if you like, unable to post here but can email if you send your addy.

    I just compared two sets I have..One pair has the date codes on the backside of the manifolds in a 7 7 5 fashion(no letter for month, July 7,65 dated correctly for the car which was built in San Jose). They also have G2 and G3 below the part#'s.

    The other pair has the date cast into the front side of the manifolds but uses a letter for the month. They also have 1 N and N 2

    below the part#'s.

    Murf, your dates may be on the backside like my San Jose K. <img src=images/icon_smile.gif border=0 align=middle>


    Not trying to answer my own question here, just noticing some differences in identical part numbered manifolds. Maybe different foundries?

    The HiPo exhaust manifolds do not follow the standard Ford date code format that appears on most other cast parts. As if that's not confusing enough, they do not have a consistant date code pattern over the years, as the examples mentioned here clearly demonstrate. They are often hard to read as well due to the roughness of the surface.
