I need help decoding this carb. Thanks for any help.

7041200
JO FA

70 ~ Prefix for pre 1976
4 ~ 1970 to 1975 (era)
1 ~ 1971 (year)
2 ~ Quadrajet (4-bbl) Federal Standards
0 ~ Chevrolet Division (also 1 or 2)
0 ~ Even number automatic (odd number manual)

Can't help with the JO FA :confused:

Thanks Dale
I think the J0 is OCT of 70 but I am not sure. But I do not know what the FA is. It should be a sept carb.

7041200 (7041201,2404,1205) is one of 4 carbs used on 1971 Chevelle models with 402 (396) and 454 engines.

FA is the Broadcast Code that would be found in the Build Sheet.

Usage
Camaro
Chevelle
El Camino
Monte Carlo
Nova
GMC Sprint
Corvette

Thanks el. Is Jo oct. of 70?
