Ford engine Numbers
I need to find out the year of my engine too and found the following, hope this helps..
Ford Engine Numbers
Small block Fords have a four digit code followed by the base number for the system cast in where the starter motor bolts to the Bell housing, the code follows a basic format and can easily be deciphered. The fist letter gives the decade the following number gives the year of the decade the next letter gives the carline and the last letter the engineering department number which would normally be Engine engineering.
So for example a number such as C5ZE- 6015 would be broken down like this.
C= Decade of 1960, 5= year of decade i.e.1965,, Z = Mustang car line E = Engine engineering this is followed by the base number for the system 6015 for base engine this is followed by a suffix which gives further information if the part has been changed.
So this is the breakdown.
Decade of Manufacture
A=1940
B=1950
C=1960
D=1970
E=1980
F=1990
The year of decade is simple the number represents the year so D9 =1979
The car line that is not really important to us for SVA information but may be of interest is made up as follows
A= Galaxie, D= Falcon, F= outside USA, G= Comet, J= Industrial, M=Mercury, O=Fairlane P= Autolite/Motorcraft, R=Rotunda, S= Thunderbird, T= Truck, V= Lincon, Z=Mustang.
The only Engineering departments of interest would be E=Engine Engineering and Perhaps X= Muscle parts and Z= Ford service parts.
Casting can also have a number that breaks down to actual casting date e.g. 6c06 would break down to 6 the year of the decade 6 for the sixth year C for the letter of the month and 06 would be the day of the month.
