Month Codes:

First year: A is January, B is February and etc. M is December. Ford skipped the letter I.

Second year: N is January (the letter O is skipped), P is February and etc. Z is December.

Second year: Only pertains to certain vehicles like 1965 Mustang's that were assembled beginning in February 1964 (introduced 4/23/1964) and were assembled thru August 16, 1965.

Knowing how Ford operates, I find it difficult to believe that they would install a 239 Y block engine in a 1953 truck. That would create a nightmare on the assembly line.

Date codes on engine blocks are foundry marks. It could be months before the engine is actually installed in a vehicle.

After being cast, blocks are placed outside to season, then are shipped to engine plants for assembly.

Then the completed engines are shipped to assembly plants where they are "banked" until needed.

These trucks are over 50 years old and have had multiple owners. Memories fade over time, so stories get all mixed up.

 

I am not seeing a stamp that has the pattern "number-letter-number". Obviously there are EBU stamps all over every part. Just behind where the front motor mount comes into the engine behind the low flywheel) there is the crazy looking stamp (can't tell what it is) followed by "48" then what looks like a backwards B. Based on NUMBERDUMMY's post, I'm guessing that likely means that is was made on the 28th day, but none of the other numbers seem to make sense. I kept thinking maybe the 8 was a B but there is no way that's true. Since there was the backwards B then I thought maybe I'm reading it upside down... but then the 4 would be upside-down.

Just above the oil-dipstick, halfway up I have 8W (thought it was a 6 at first but seems to be an 8 looking closer). There are only two stampings. The 8 also has a raised square around it.

I have a picture of the motor mount... just need to figure out how to post it based on the READ FIRST post.

I am more confused than before looking at the numbers...

 

Front motor mount:

 

48 backward B using the logic I learned of would probably be August 26th or 27th 1954.

8W, maybe August 28th.

Bill, do you know how to decipher the Y-Block date code? It seems to be slightly different than later codes and the earlier flathead codes and the use of letters or numbers doesn't seem too concrete. I've been searching y-blocksforever for the date codes people have asked about. It seems like the first is always a number. The second and third seem like they can be either or.

 

I just saw your picture. I think it's safe to say it's not original. That looks to be a mount for a car, and a pretty sorry installation at that. I can't believe there's any way Ford would let it roll of the line like that. A genuine truck mount will look a lot better and fit well, as designed, on the frame rail.

 

Yummm, do any bolts go thru the front (toward the right side) of two holes? Looks like someone drilled holes in the Y-Block mount so it would line up with the frame crossmember.

I would have to say that doesn't look "Factory" and whoever did it took a few short cuts. Of course this is just my 1¢ worth.

You might try Love Ford http://www.lovefords.org/ for help with your numbers. Also take into account that "numbers" are not always accurate.

 

thought i'd add my 2 cents worth ,,,my dead stock 55 F250 239Y front engine mount looks nothing like that .. it stops at the front edge of the crossmember...dosen't have the raised circular shape on top and none of the hanger stuff you have sticking out past the frame crossmember .. i'd go with the car Y mount charlie thinks it is ..

 

If anyone has the 1948/56 Ford truck parts catalog, there is a picture of all the 1954/55 Y block front engine mount components. None look like the photo above.

Pic will be found in Illustration Section 60, page 158, upper left. The same setup was used thru 1964 for all truck Y blocks, and 1955/57 Thunderbirds.

Basically an L shaped bracket bolts to the front of the engine. One steel/rubber rectangular insulator bolts to the L shaped bracket, then to the crossmember.

Below the crossmember is a donut shaped rubber insulator. A steel tube and bolt passes thru the lower/upper insulator/L shaped bracket, than a nut ties the whole tamale together.

At the rear, left/right upper U shaped rectangular insulators bolt to the engine, then to the crossmember. Below the crossmember, are rectangular insulators. Another steel tube and pass thru bolt and nut are used per side.

This three point mounting system is different for 1954/62 Y block Ford passenger cars.

Y blocks installed in 1954/62 Ford passenger cars have right and left steel/rubber insulator that bolts to the crossmember, then to the block.

At the rear, one steel/rubber insulator bolts to a bracket that is made as part of the transmission's extension housing, then to the crossmember.

 

Sherbo, unfortunately all of us EXPERTS (ha, little joke there) appear to agree that your installation of a Y-Block was not original to your truck. I wonder what the other mounts look like??

In addition to what you stated, '54-56' cars also had the "steady rest" at the front like the one in Sherbo's photo and mentioned by Charlie.

 

numberdummys descrption in his 1;13pm post is my 55s 239 mount to a T ,,, thats exactly what it is ...being the 2nd owner of a very low mile truck mines a great example of dead stock under the hood ..ha i just replaced the orig distrib cap and plug wires <have the "Ford" on the plug caps> only took a week and 3 trips to the parts store ,,, onliee order for the wire hangers rubber blocks .. well you get the idea ,,

 

Here's a truck mount.
Mine started life with a 223 which is why it looks a little different on the cross member.

 

I didn't mention the right/left front engine mount steady rests because only 1955/57 Thunderbirds used them. You won't find these on any Ford passenger car.

Pictured in the 1949/59 Ford passenger cars parts catalog, Illustration Section 60, page 163.

 

Bill I was not referring to the T-Bird side steady rests, I was referring to the front steady rest on '54-56' passenger cars, which is what is pictured in Sherbo's photo. I wasn't saying you were incorrect, I was just pointing out that Sherbo's front mount was off of a passenger car.

Many cars you see these days the front steady rest has been left off because it was "deemed useless".

 

The only thing the 1949/59 car parts catalog shows for Y block Ford passenger cars are the right and left front steel/rubber insulators, which are the same right/left and fit 1954/58 Y blocks and 1958's with 332/352's.

Updated Ford part number: B7A-6038-B.

Where is the steady rest for these cars? No see um. Why would they be necessary, considering how the engine is mounted?

Since the Bird's used the same front setup as the trucks, these have right/left steady rests.

 

It bolts to the timing cover and then to the frame with a rubber mount under the radiator.
