Hi All,
I have a 68 Camaro CA car with the smog pump and from what i can see online i need a Carb with numbers starting with 703. But im struggling to find any, all i can find online are starting with 702.
Can anyone please help confirm this and or advise where i can find the right carb for CA car 396 Quadrajet 4bbl and Auto trans

 

I would suggest looking at the CRG website page that gives more detailed information on the carbs used in 1968. It lists the carbs by number that were used on the different motors and horsepower ratings.
