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

8hspace.gif (810 bytes)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.
8hspace.gif (810 bytes)The numbers include the model number, usually 7 digits, a change letter, signifying changes during the model year, and a date code.
8hspace.gif (810 bytes)The stamping or part number decodes as follows:

Example: #70 2 8 2 1 9 DG 1938

Carter-built Rochester Carburetors

8hspace.gif (810 bytes)Carter built Quadrajets for General Motors in the 1960's. All Carter-built carbs have "MFG by Carter" cast into the carb body. The carb number matches the Rochester number.
