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.
- 2 - Decade produced.

- 4 - 1970-1975

- 8 - 1980's
- 8 - Year produced. 8=1968
