On a 1966 GTO
 
X2 on the Carter AFB.

In '66 the OHC 6 with Sprint/Sports package was the only model to get the all new Q-Jet.
GTO didn't see it until '67

Here's a pair of the 4034S AFBs on a repro 'bathtub' tunnel ram. These carbs are rated at around 575 CFM each.

Thanks, for the quick reply. Mine has the Carter AFB so I guess I have the correct carb. I'm new to Pontiacs and GTO's. Just curious Here is a picture of my car Where would the carb number be located?

Nice car! And welcome.

The '66 guys will weigh-in, but the carb should have either a metal tag on the right rear under the air horn (drivers side) or a stamp on the left front of the throttle body near the idle screws (possibly both stamp and tag). Should be 3-4 digits followed by an "S" if it's a Pontiac AFB.
