I think you might be missing some numbers after the OA.

Does this help:
http://www.mustangsandmore.com/ubb/FordTechData.html
The first two digits indicate year. The letter is the decade;
A = '40s
B = '50s
C = '60s
D = '70s
E = '80s
F = '90s
G = '00s

The third digit designates body line;
A = Ford full size
D = Falcon
E = Escort
F = Pinto, Maverick, Falcon
G = Early Comets, Montego, Cyclone
H = Medium/Heavy Duty Truck
K = Edsel
L = Lincoln Mark VII
M = Mercury
O = Fairlane
R = Capri
S = Thunderbird
T = Pick-up Truck or Bronco
U = Econoline Van
V = Lincoln
W = Cougar
Z = Mustang
{there are actually many more}

The fourth position signifies Engineering group;
A = Chassis
B = Body
E = Engine

If it's a Service Replacement part;
Z = Ford Division
Y = Lincoln-Mercury
X = Original Muscle Parts program
M = Ford Motorsport, SVO, FFRP

The center number, four or more numbers or letters, is the part number.
The A at the end of the number indicates that the part is the first version. If it was revised once, it would be B. If it was revised again, it would be C, and so on. When they run out of letters, it becomes AA, AB, and so on.

So if we decode this number, D1ZZ-6675-C, we come up with the
following:

D1 = 1971 model year.
Z = Mustang.
Z = Ford Division Service Replacement part.
6675 = the group number for oil pans.
C = The third version of this part.

Also, have a look at this discussion here:

Smile oops

Thanks to the guys who replied .... Have discovered it really is a D2AE-CA - which is a 1972 351 ..... The C, really does look like an "O" where the open end of a C is just a tiny thin line (which of course had grease filling it up to complete the look of an "O"

thanks again.

The casting number is not the whole picture. Have a look at the engine number (stamped above the fuel pump) and then have a read of this site:

XM and XP had earlier 200 CID with 4 main bearing cap blocks (3-freeze plugs and 3 bolt water pump).

* 250ci -7 main: 4 bolt water pump and 5 freeze plugs.
* 200ci -7 main: 3 bolt water pump and 5 freeze plugs.
* 200ci -4 main: 3 bolt water pump and 3 freeze plugs.
* 170ci -4 main: 3 bolt water pump, 3 freeze plugs, and a T code (or no code).
* 144ci -4 main: 3 bolt water pump, 3 freeze plugs, and an N code.
