This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern. If you have a spreadbore style intake manifold, you will need an adapter to install this carburetor. Similar to the Mr. Gasket #1932.

Overview

While modifying a street carburetor for circle track applications can work reasonably well, Quick Fuel Technology's Q-Series circle track carbs eliminates the guesswork and offer substantial advantages in adjustability, consistency, and predictability. Since racing around a banked oval pushes fuel to the passenger side of the car, Q-Series circle track carburetors feature die-cast aluminum fuel bowls with internal baffles that eliminate slosh. The bowls also feature an integrated fuel chute that substantially reduces aeration, and directs fuel toward the main jet pickup area. To assist in flattening out the fuel curve, screw-in air bleeds enable fine-tuning of both the low- and high-speed systems, while a proprietary booster design enhances carb signal without restricting high-rpm airflow. Helping drivers put the power down is an adjustable QuickLink system that allows changing the opening rate of the secondaries to 40-, 60-, or 100 percent. Circle track Q-Series carbs are available in 6 different sizes ranging from 650-1,050 cfm for both gasoline and alcohol applications. All Q-Series circle track carburetors are equipped with roller bearing seals which provide smoother throttle response, less wear on shaft, and longer life. •Lightweight aluminum main body •Vacuum and mechanical secondary models available •Aluminum fuel bowls with dual sight glass windows •Billet metering blocks with 4-corner idle system •Changeable idle feed and power valve channel restrictions •Billet aluminum throttle body provides exceptional precision and strength •PTFE coated and sealed shafts that have been slabbed for added air flow
