I had a 1963 with the SD 4-barrel, which was entirely TOO LARGE for the street. Removed the SD 4-barrel and replaced it with a Carter AFB part number 9400s (400 CFM). The before and after were like driving two entirely different cars.
As far as reliability is concerned, while I feel the Rochester 2 barrel and 4 barrel carbs of this period are among the most reliable carbs ever built, sadly, cannot say the same for the 1 barrel (type B or BC). MAJOR design flaw that requires work every few years. The Chevrolet guys toss the Rochesters in favor of the Carter 1 barrel type YF. Jon.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
