Yours would be a '75-'77 block. Don't remember all the misc. stampings on the pads but it surely isn't a '67 vintage block.

Thanks For The Response

Thanks, I have been arguing with my son-in-law about where or what that pad number is and we both think it was a mis-stamp, for 76 not 67, looks like one of my 'senior moments'

With the casting number the guy that started this post being D4AE-6015-AA3, wouldn't this be one of the beefier heavier 351 blocks even though one person responded that it is a 75'-77 model.

I have an engine in an 82 F-100...The motor was in the truck when I bought it, and the guy told me it was a 351w....I am trying to put a rear main seal in it..and all the seals I keep getting are wrong...I wrote the engine block number down and no-one can tell me what it is... the block number.. D4AE-6015-AA3....

first digit refers to the decade (60's = C, 70's = D) while the second digit refrs to the year within the decade, or 1974.

Easy 351W versus 302W check: measure across the width of the engine's intake manifold bolts, center-to-center. A 351W is 9" across (9.5 deck height) and the 302W is 7.7" across (with the 8.2" deck height).

1969. D4 was for 1974, but could be used until all blocks that were cast were used up. Joe-JDC.

quick-check for 351 vs 302

September 22 2009, 11:33 PM 

Just look at the parting line between the head and block relative to the water pump ports on the front cover. 302 is flush. 351 is an inch away. Distributor hold down boss, 302, flush, 351 an inch below the valley gasket surface. Don' need no steenkin tape measure....

RH machine pad numbers are hot test stamps

October 6 2009, 10:26 PM 

The assembly line was installed in 1969 with the first engines rolling off the line in 1970, you are correct.

If the number is metal stamped on the small machined pad on the RH side front and perpendicular to the ground it is a hot test inspector's stamp. They were made to show month, day and the last two numbers of the inspector's 4 digit badge number. This one is a '74 casting with a May 11 hot test date, inspected by xx67

Each engine made at Windsor Engine Plant 1 was tested in one of 48 stationary hot test stands for a minimum of 6 minutes, most had >10. After timing, an inspector would check for the obvious things like leaks, etc., balancing marks (crayon green or red number on LH rear rocker cover) and timing stamp (a letter stamp below the inspector stamp), stamp it OK and pull the fuel feed.

....good ol' days....

Not sure how cool, but fun sometimes....

October 7 2009, 8:58 PM 

...and learned a lot. Seems like a "Galaxie" many years and far, far away now. (get it? I kill myself). I did work there for a long time in the 70's and started engines in the HT and moved through a bunch of jobs as they became available. Ended up in engineering and processed powertrain assembly lines in 80's 90's to now for the V6 lines in Cleveland. Try to help now and again with an answer I am sure of.

I hate to disagree with someone who was involved with the process but the 351 W was avail in 1969.

I own a 1969 Mustang GT that was produced in the Metuchen plant in Nov. of 1968 for model year 1969 that was an H code 351 2V Windsor car.

These cars came with the C9 prefix blocks - which I have had a number of.

Entirely plausible, many early engines were made...

...on the original 260/289/352 line that was there before the new one in '69 specifically built for the 351W with new automation. My earlier post was somewhat misleading.

Another stamp question for DMS

December 26 2010, 8:47 PM 

DMS,
I know this thread is OLD, but maybe you still check it and can give me an answer.

On the front of my 302 block, is a number stamped in to the block. The number is stamped in to the mounting boss (or what ever you'd call it) for the water pump, top right bolt hole, as you are looking from the front of the engine bay. Link to pics here:

http://i564.photobucket.com/albums/ss86/akafrankcastle/1972%20Sport%20Stropped/DSC00650.jpg

The number stamped is "1B19E"

http://i564.photobucket.com/albums/ss86/akafrankcastle/1972%20Sport%20Stropped/DSC00663.jpg

Any ideas what it means?

Bob,
Thanks for the response. Based on the link you sent, it appears the numbers I am talking about are the date of manufacture (most likely date of assembly).

The block in question is a D1OE-6015-AA. It carries a casting number of 1A21 (January 21, 1971). The number stamped in to that boss or ear where the water pump bolts on is 1B19E (Febrary 19, 1971 I'm thinking). But the extra digit, "E" is what is throwing me off.

I'm not doing any kind of a numbers matching restoration here. It's a 1972 Bronco with a date of manufacture in November 1971.

I'm just super crazy about tracking down any and all numbers I find in my projects so I don't run in to issues down the road.

Not sure....

January 3 2011, 1:03 PM 

either what the final E stands for. Each foundry had internal codes for their own use....not thinking decades later that it would drive Ford fans crazy! It is a regular production line block though.

Ford's engineering & casting/foundry departments back then sometimes didn't even follow their own protocols, but this usually involved the rare XE prefixed parts (meaning experimental). Sometimes even these parts carried no numbers at all! Go figure.
