Carter AFB Competition series

[Neal Zimmerman]

I got his carb on a 63 Belvedere i bought once with a 318 poly.. Was this an off-road version of regular AFB? I had never seen that label before. I know the Thermoquad competition series was supposed to be off-road only (I think).

I had two of them on my 1963 Stage II 426 Wedge with the crossram manifold back in the 1970s.
