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= Lincoln, 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.
A-Jan, B-Feb, C-March, D-April, E-May, F-June, G-July, H-August, J-September, K-Oct, L-Nov, M-Dec

good info mang

Hmph, so my heads are from a Fairlane. Good to know. I didn't realize the casting numbers also had the car line in them.

Most normal (non-Boss) small-block heads have the Fairlane code since the small block was originally designed for it. This doesn't mean they originally came from a Fairlane.

Sometimes you'll get some heads with the A, D, Z, or T for the model position. And sometimes the great S, which means you have junk 255 heads (E0SE-AC).

They're a D0OE casting. I had been asking for Galaxie 500 parts since they had a 351w in 1970 but now I guess I can also ask for Fairlane parts. Same difference, 1970 351 spark plugs should all be the same. Its just interesting information. The E7te head is from a truck, etc etc. Kinda cool to see where the original engineering came from vs the actual application.
