Restoring the original Quadrajet carburetor will preserve your Corvette's value. You should avoid purchasing a "rebuilt-exchange" carburetor. Due to the mass-produced, similar architecture of the Quadrajet, a host of applications will fit your Corvette engine's manifold. However, neither a Buick 231 V-6 nor a 454 V-8 application will have the fuel metering components or tuning calibrations for a Corvette 350 V-8. Keep the original castings, jets, and metering rods!

Use quality parts when rebuilding a Quadrajet. Modern carburetor kits contain extra gaskets to allow wider model coverage. Be careful when matching gaskets to the originals. Small differences can create air or fuel leaks and poor performance. The stamping number on the carburetor identifies the carburetor's original application and the gasket kit needed.

Find a clean, dust-free place to work on your carburetor. Follow the steps shown and use a factory workshop manual to confirm specifications. Compare details with the instruction sheet found in a quality rebuild kit. Properly restored, your Corvette's Quadrajet will provide years of impressive performance-and fuel savings, too!
