I am trying to find out what this code means (F422D). It is on an old chevrolet engine from the 1960's.?

Question

This engine is in a 1957 Belair. I don't think the engine is the original. I don't know if this is the date code or just the engine code.
Please help.

Answer 2

Where did you get that number? F422D dosent look like a date code. See example below
Engine Code Style Pre '70: F0114MB
F=Assembly Plant
01=Assembly Month (MM)
14=Assembly Day (DD)

Engine Assembly Plant Codes:
F - Flint Motor Plant
K - McKinnon
M - GM of Mexico
S - Signaw Service
T - Tonawanda Engine Plant
V - Flint Engine Plant

Motor Division:
C - Chevrolet passenger car
T - Chevrolet truck

Close to the engine suffix code is the partial VIN code. Partial VIN example:
"18U199887" decodes as "1"=Chevy, "8"=1968, "U"=Vehicle assembly plant Lordstown, Ohio and "199887"=last six digits of VIN.

VIN Assembly Plant Codes:
A - Atlanta, Georgia R - Arlington, Texas
B - Baltimore, Maryland S - St. Louis, Missouri
C - Southgate, California T - Tarrytown, New York
C - Atlanta, Georgia (Doraville) ('64 only) U - Lordstown, Ohio
D - Atlanta, Georgia (Doraville) U - Southgate, California ('64)
F - Flint, Michigan W - Willow Run, Michigan
G - Framingham, Massachusetts Y - Wilmington, Delaware
H - Fremont, California ('64 only) Z - Fremont, California
J - Janesville, Wisconsin 0 - Oshawa, Canada ('65-'69)
K - Kansas City, Missouri 1 - Oshawa, Canada ('70-)
L - Los Angeles, California 1 - St. Therese, Canada ('67-'69)
N - Norwood, Ohio 2 - St. Therese, Canada ('70-)



Chevy engine casting numbers are located on the back of the block most often on the left (drivers side) on top of the bell housing flange. The Engine Suffix Code is stamped on a block pad located immediately forward of the right hand or passenger side cylinder head. Some blocks may have the block date codes listed on the passenger side of the block. If you have an early big block or a late model small block, then the block casting date may be located on the passenger side of the engine block instead of the rear ledge of the block.

Most any Chevy dealer has a book on engine numbers and can tell you
