Carburetor

Holley

Holley carburetors have been used on high performace engines since the early '60's. Their modular design, inclorporating a metering block for the jets and power vales, made it easy for anyone to rebuild their carburetor.

The air horn of the carb will be stamped with several numbers, including the Holley list number, the Chevrolet part number, and usually a letter indicating the application. There is also a date code.

Rochester

Rochester Carburetors were used on all standard performance Camaros. There are three types of identification on Rochester carbs. Models B, 2G, and 4G used a triangular metal tag installed beneath the air horn screw. The early Model M (Monojet) and 4M (Quadrajet) used a circular tag in a cavity in the side of the float bowl. Other carburetors used a stamping on the body of the carb.
The numbers include the model number, usually 7 digits, a change letter, signifying changes during the model year, and a date code.
The stamping or part number decodes as follows:

Example: #70 2 8 2 1 9 DG 1938

70 - Prefix code. "70" will appear on all late '60's Rochester Carburetors. All Rochester Carburetors built from 70 - 75 should have a "70" prefix but could be missing on some carburetors. In '76 the prefix changed to "170".
2 - Decade produced.
- 2 - 1960's
- 3 - 1060's with A.I.R.
- 4 - 1970-1975
- 5 - 1976-1979
- 8 - 1980's
8 - Year produced. 8=1968
2 - Model
- 0 - Monojet (1 bbl) Federal standards
- 1 - Two jet (2 bbl) Federal standards
- 2 - Quadrajet (4 bbl) Federal standards
- 3 - Monojet (1 bbl) California standards
- 4 - Two jet (2 bbl) California standards
- 5 - Quadrajet (4 bbl) California standards
1 - Division. 0, 1, and 2 all indicate Chevrolet.
9 - Transmission
- Even numbers - Automatic Transmission
- Odd numbers - Manual Transmission
DG - Customer code.
1938 - Date Code. The actual day and year the carburetor was manufactured. First three digits indicate the exact day of the year. Last digit reflects the year of production. Ex: 1938 = 193rd day of production in 1968 (depends on decade).
