Does anyone have a block between the following numbers: A31313 through A45396?

Need some information off of it providing it is not a RESTAMP.

Thanks.

Hi Steve. I've got a 1930 Model A Tudor Sedan Engine #A3138425. I believe it's the original motor from the car. The car still has all original interior. I've posted pics on Ford Barn before. Let me know what info you might not. The block is not a restamp.

Doug,

Are you able to see inside the block for some key features?

I've got it stripped down and ready to clean. It's pretty decent on the outside and nasty on the inside - lots of critters lived in here!

I have engine No. 41xxx. It is on a bench, so I can check the internals.

Steve Plucker · 08-31-2011, 04:26 PM

Doug,

Here is what I am looking for:

MIDDLE OIL DAM HEIGHT FROM INSIDE BASE OF VALVE CHAMBER TO TOP OF DAM

1-1/16 INCHES # 31,313 FEBRUARY 23, 1928
1-7/16 INCHES # 45,396 MARCH 12, 1928 (14,083)
(CONTINUED THROUGH END OF PRODUCTION)

FRONT OIL DAM HEIGHT, ABOVE OR BELOW TOP OF PUSH ROD BOSS

1/4 INCH ABOVE # 31,313 FEBRUARY 23, 1928
1/4 INCH BELOW # 45,396 MARCH 12, 1928 (14,083)
(CONTINUED THROUGH END OF PRODUCTION)

What is your A33XXX block?

Thanks Doug.

Steve -
Last night I chased away some of the critters that have nested in my early '28 engine block. I checked the features that you requested plus I looked at the features that you wanted Richard to investigate. Also, I checked my engine's production date and found that it was produced on Feb. 28, 1928. Here's what I discovered:
Middle oil dam height = 1-1/16"
Front oil dam heigh = 1/4" below the tappet boss
Water outlet hole, center of block = Elongated
Additional ribs at rear main bearing = Ribbed

Clearly this data does not neatly fit your assumptions. Often there was not a clear demarcation in the introduction of new features on the Model A. In the case of engine blocks, there was a short curing time before they were sent for machining and assembly. Any storage of parts was done on a lst-in first-out basis. Therefore, for period of time, older designs are produced along with the newest design. In the case of my engine, it has the later features so it must not have had much of a cure time and went quickly into production.

Also, as you know, the "release" dates are not absolute. The change(s) may have occurred prior to the "release" or in some cases well after that date.
