Hemi Exhaust Manifold Foundry Mark - 10/26/20 09:12 PM
I have run into a wall trying to decipher the date codes on my Hemi manifolds. So, I am going to try a different route. This is what I believe to be the foundry mark looks like on mine. Does anyone have a manifold with this foundry mark that is more legible? If we can identify the foundry mark, maybe I can round up the foundry and get some info. I don't believe these were made by a corporate foundry as it seems corporate used the month-day-year format. We are going to skin this cat somehow.
