Probably a date code either 83 or 93 manufactured( 73 but probably not as the coding was a little different ). Look lower on the head for a 4 digit code something like E3TE etc. That will tell you more.

Ok I was gonna post this when you first asked but due to technical issues I gave up! Now I finally got the pic you need. Look at the pic as it shows where you can find the part number. If the heads are not off you wont be able to find out. Ford part numbers go in order by letter for the first character. C is 1960, D is 1970, E is 1980, F is 1990. The second character is going to be the number in order. For example 1968 would be C8. Ford part numbers always start with a letter and number followed by 2 more letters. The 3rd and 4th letters designate Model and Design Engineering office.
Here is a site to better help you figure out the part number its Australian but is still a good example.... Edited by Blueoval76 - 30-March-2013 at 9:06AM |

Awesome, I was just going to post a pic .
Numbers break down for ford. Ford makes it really easy to read their casting numbers when you know what you are looking at. Make sure you also understand that the casting numbers are not the same as part numbers or engineering numbers. Here's how a typical Ford Casting number breaks down. Let's use C5AE-6015-A as out example in decoding the casting number. The First position indicates the decade: B = 1950-1959 C = 1960-1969 D = 1970-1979 E = 1980-1989 F = 1990-1999 The Second position indicates the year of the decade: C5AE-6015-A So we know this casting is from 1965 The Third position indicates the car line A = Ford D = Falcon G = Comet, Montego, Cyclone J = Marine-Industrial M = Mercury O = Fairlane&Torino S = Thunderbird T = Ford Truck V = Lincoln W = Cougar Z = Mustang So thus far we know C5AE-6015-A means 1965 and the car line was Ford The Fourth position indicates the engineering group: A = Chassis Group B = Body Group E = Engine Group If the item is a service part, the fourth position then indicates the division. Z = Ford Division Y = Lincoln-Mercury X = original Ford Muscle Parts Program M = Ford Motorsports SVO or Ford-Mexico The four digit number (6015 in the above example) indicates the basic part number. The basic part number tells us what the part is. 6015 in the example tells us it's an engine block. Or the number 9510 is for carburetors and so forth. Every ford part has a basic part number, all the way from brackets to nuts and bolts. This makes finding certain parts awhole lot easier in fords master catalog. The last character in our example C5AE-6015-A is the suffix. "A" means an original part, "B" means the first revision of the part, "C" means the second revision, "D" means the third revision and so forth. During the hectic days of constantly stiffer emissions in the 1970's it was very common to come across a cylinder head that had AA or AB stamped on it. Meaning many revisions as they strived to meet emission regulations. So in conclusion let's look at our example C5AE-6015-A The above part was casted in 1965 for the Ford car line in the engine group, it is an engine block and was an original part. |

get the break down as stated above But do you know what "GA" means.
My 351c 4 bolt main block is stamped D2AE GA 1K29 which I believe would be 1972 Ford ( No Specific Car) Engine (Component) "GA"? 1971 Oct 29 was when it was cast Thanks for any help |

I believe that the many of the 1972-1974 Q-code 351C "Cobra Jet" engines had 4 bolt mains.And some of the the 1971 R-code "Boss" 351C engines, had 4 bolt mains also.
And most of the 351C 2V engines had two bolt mains.

in your example - (C5AE-6015-A), C5 designates the design year of the part (1965) not manufacture date, this part may have been used for many years, and may be updated several times (suffixes) but until a major redesign, it would still be C5AE-6015-(+update suffix) regardless of date of casting.

The 4 bolt main has been discussed many times. I think we can safely say you really don't know until you pull the pan off.-Rick-

Yes, you will find many 72 castings in cars all the way through ... until they ran out of them. |

-GA is just a casting code suffix, it doesn't 'mean' anything but simply distinguishes that casting from another
-GA does happen to be the correct cast code for the Boss 351 cylinder head though, but not all -GA heads are necessarily Boss 351 heads. any casting can be machined to a low spec or a more desirable spec such as the D2AE-CA 351C block... they can be found machined as both 2 bolt mains and 4 bolt mains possible a -GA cylinder head can have pedestal rockers or screw-in studs & be machined for spring cups and it gets even screwier, Ford would use various parts of core boxes years apart to create a different part than the first run that carried that cast code. example is the 351C XE or Australian Nascar block, same cast codes years apart one is a 'pillow' block while the other is regular with other differences too this means that the date code can also play a part in the ID |

"nutshell"
Those engineers recycled parts years later as well. 351 Lightning uses a 70s Torino camshaft...
