| Casting and Date codes |

If you look (from the bottom of the block) at the bottom of the pad where the oil filter adapter mounts, you will see the raised, cast-in production date code.
The format is '#A##' (like 6K23), where the first # is the Year ('6' indicating 1966), 'K' is the month (October), and the two-digit '##' is the Day of the month.
At the top front corner of the block is a casting used to locate the block in the factory jigs. This may have a date code stamped into it, indicating the actual date of machining (as opposed to casting). It would be something like A10, for January 10th. Obviously, this would always be a later date than the casting date.
The raised casting number, something like C7AE-A, would be on the passenger side of the block, about halfway up near the front. Except for a few instances, this number is practically meaningless, as many engines of different displacements shared the same casting number.
There's a flat pad at the top rear of the block, beneath the driver's side cylinder head. Any VIN number (usually a partial number only) would be stamped there. However, Ford used these pretty infrequently prior to the very late 60's. |
