Overview

A Stage 2 starts with all of the modifications of a Stage 1 and features a 1.75 throttle bore (butterfly) versus a 1.690 that is stock. This increases airflow and also helps equalize fuel distribution in the intake manifold. This is commonly referred to as a "Cheater" carburetor because it passes any inspection as long as it is not removed from the manifold.
