Topic: 289 (65-67) Block Date Stamp Study/Survey

[J_Speegle]

Figured we would start small and focused study then we can move to later years and other engines once we get this step addressed and if it bears any fruit

The question - Is the assembly date and assemblers initial stamped on the small protrusion at the front drivers side of the block where the head attaches the assembly date of the short block or the completed engine?



For years we have taken it to mean the completed engine but let's see what the findings suggest and discuss

To collect information we need at least

1- Engine block casting date




2- Assembly date stamped on the small extension/protrusion




3- Casting dates of the heads, intake, dist, exhaust manifolds believed to be original to the block





4- Engine ID aluminum tag information





The findings may not be as defining as other surveys since individual items could be cast before and installed after if that was what was done.

Lets see where this leads us

Thanks for viewing and considering participation

Jeff, here is the info from my car.  I've added a few more items to what you originally requested, and also noted what I know is not original.  I can dig out the harmonic balancer later if needed.

Jeff: did you get the codes from the red '65 coupe you helped with?  I have the engine apart, can get all the info if needed.

Note 1:  Original 289 engine is still in the car. In June 1983 the engine was rebuilt and re-installed (long block) at 293,450 miles by an authorized Ford reman facility in San Diego.  The car with Ford reman engine now has logged a total of 541,000 miles, or an additional 248,000 miles since the rebuild. 1983 Ford rebuilt engine warranty: )

Note 2:  During the engine reman process, the RH cylinder head was not suitable for reconditioning and replaced with a '67 289 Thermactor head cast in July May 1967. Distributor was replaced during engine reman with a Ford service part.

Jeff,

I don't have all my dates but two of the dates I have are relevant to the question you are researching.

Assembly date: 5M1
Intake Manifold Casting Date:  5M3

[J_Speegle]

Deuce - Same markings on Trans and steering??

Steering box has a cast date on the main body and a tag (assembled) date on the tag

Thanks guys for the continued input and support of this study
