Ford part / casting numbers
This information refers to part numbers and casting numbers. Your distributor might be stamped "FEK-12127" but the parts book calls it "B7A-12127"
Ford part numbers follow a system introduced about 1954 to help identify parts. The first
digitindicates the decade of the part’s introduction. The second digit is the year of the decade the
part was introduced. A few parts that predate 1954 appear to have been given this type of number.
A=1940's a few parts seem to have been given this prefix sometime later.
B0=1950 C0=1960 D0=1970 E0=1980 F0=1990
B1=1951 C1=1961 D1=1971 E1=1981 F1=1991
B2=1952 C2=1962 D2=1972 E2=1982 F2=1992
B3=1953 C3=1963 D3=1973 E3=1983 F3=1993
B4=1954 C4=1964 D4=1974 E4=1984 F4=1994
B5=1955 C5=1965 D5=1975 E5=1985 F5=1995
B6=1956 C6=1966 D6=1976 E6=1986 F6=1996
B7=1957 C7=1967 D7=1977 E7=1987 F7=1997
B8=1958 C8=1968 D8=1978 E8=1988 F8=1998
B9=1959 C9=1969 D9=1979 E9=1989 F9=1999
The 3rd digit indicates the type of vehicle the part was intended to be used on.
A= Full size Ford. 50's Fairlane, 60's Galaxie & LTD ect.D=FALCON
J= INDUSTRIAL
G=COMET
K=EDSEL
L=LINCOLN
M=MERCURY
O=Intermediate sedan. 60's Fairlane, Torino
Q=HEAVY DUTY TRUCK
R=SPECIALTY-HIGH PERFORMANCE

3rd digit indicator by model. Sedan includes convertible, wagon and sedan delivery.4th digit indicates the category the part belongs to. Engine, chassis, wiring, fuel system, ect.
The next digit indicates whether a part is for an engine, chassis ect. Engine parts are "E" while chassis parts are "C". This digit was not used in early part numbers. This designator was added around 1959. Z indicates a part has been changed but will still work on previous applications.
Individual castings generally have a 4 digit number to identify the part. Occasionally a part such as a distributor had a 5 digit identifier. Many of these numbers have not changed over the years. An intake manifold for a 1954 pick-up is a 9425, the intake manifold for a new Mustang is a 9425.
A few common numbers
PART | CASTING NUMBER | PART NUMBER |
INTAKE MANIFOLD | 9425 | 9424 |
HEAD | 6090 | 6049 |
BLOCK | 6015 | 6010 |
DISTRIBUTOR | 12127 | |
CONNECTING ROD | 6205 | |
CRANKSHAFT | 6303 | |
CAMSHAFT | 6250 |
The suffix after the part identifier indicates the size or type engine the part fits. This is not constant. A ’64 292 truck block has a "C" suffix but the '64 pick-up cylinder head has a "D" suffix.
Therefore, B9AE 6015 F is a 1959 full size Ford engine block. C2AE 6015 C is 1962 full size Ford engine block. If a part was not changed the part number would not change. A 1964 Truck block is also a C2AE 6015 C.
The 1957 cam for supercharged engines was part number B7A 6250 C. This indicates it was intended for passenger car use as opposed to being Thunderbird specific.
