==Advantages== [[Image:Rochester-Quadrajet.jpg|250px|thumb|right|The Rochester Quadrajet mounted on an aftermarket aluminum intake manifold]] Significant positive features of the Quadrajet were: # Economy. Unlike most other 4-barrel carburetors, the Quadrajet has a drastically different sized primary and secondary bores. The much smaller primaries act as a small two-barrel carburetor until you press the throttle enough to start to open the secondaries. The small primaries allow the primary throttle plates to be opened wider, and thus making the carburetor more efficient than a large two barrel, or square bore four-barrel. # Drivability. The small primaries also create better throttle response at part throttle application. The Quadrajet had a centrally located float that gave it excellent fuel control resulting in excellent street manners. # Off Road. The Quadrajet’s centrally located float is highly resistant to level changes caused by cornering or acceleration.
