Corvette C3 VIN Decoder
VIN (vehicle identification number) number is stamped on a plate riveted to the bottom front face of the driver's windshield pillar and it is visible only through the glass.

The VIN consists of the Division code (Chevrolet), car series (Corvette), body style (coupe/convertible), engine, assembly plant (St. Louis/Bowling Green), and serial number (sequence). During the Chevrolet Corvette C3 generation, there were three different forms of VIN.
- 1968, 1968, 1970, 1971: 194379S100001 (13 characters)
- 1972, 1973, 1974, 1975, 1976, 1977, 1978, 1979, 1980: 1Z37K2S500001 (13 characters)

Chevrolet made a total of 542,862 C3 Corvettes.
The model year was three to four months in advance of the calendar year, so the year of manufacture of the body may be earlier than the model year.
Corvette C3 VIN Decoder automatically detects the format of the VIN and calculates the body built date from the sequence number.
If you want to know the birthday of your Corvette, you can find out with this calculator.
C3 Corvette Trim tag decoder
a trim tag or trim plate is a steel plate located directly above the driver's upper door hinge.

The trim tag consists of a body build date, trim code (interior color, leather/vinyl/cloth), and external color code. Chevrolet had recommended color combinations, but the buyer could order any exterior/interior color combination they wanted.
The body build date is the date when the partially assembled and painted body got the trim tag. The car's final assembly date is typically several days after the body build date.
The C3 Corvettes used two trim tags, the cars built at the St. Louis plant (1968-1981) there is written "Chevrolet" at the top, and the cars built at the Bowl Green plant (late 1981 - 1982) begins with the letter B or C, depending on the year of manufacture.


Because the 1968 - early 1981 trim tag does not have a year mark, it must be entered into Corvette C3 Trim Tag Decoder when decoding.
Engine code, partial VIN, block casting code
Engine code (assembly date and suffix code) and partial VIN code is stamped into a pad at the front passenger side of the engine near the water pump mount area.
The engine block casting number is located on the flange that mates to the transmission bell housing.
All the Chevrolet C3 Corvettes engines were marked with an engine code at the engine assembly plant, which indicated location, date, and limited engine specifications (engine code suffix).
When the engine arrived at the body assembly plant, it was stamped with a partial VIN code consisting of a divisional code, assembly plant code, and the VIN sequential number.
Engine suffix codes may be reused over time, so you must also check the partial VIN code.
The block casting number identifies the years in which the block was in use and the cubic inches.
Corvette C3 Decoder also recognizes engine and block codes other than those used in the Corvettes.

Quadrajet part number
The Quadrajet is a four-barrel carburetor, made by the Rochester Division of General Motors. It was used in all C3 Corvettes except in 1981 when crossfire injection replaced carburetors. Alongside the Quadrajet, Holley carburetors were also in use from 1968 to 1972.
Quadrajet identification information is stamped into the main body on the driver's side.

The part number shows the year of manufacture, type of carb, division, and whether is it a manual/automatic transmission model.
Corvette C3 Decoder Quadrajet part number decoder recognizes carburetors used originally in the Chevrolet Corvettes.
