            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 digit

indicates the decade of the partís 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

S=THUNDERBIRD

T=TRUCK

V=LINCOLN-MERCURY DIVISION

Z=MUSTANG

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 í64 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.
