Custom Built Quadrajets

Our shop supplies the core and builds a Quadrajet for your engine. Choose a QB1c custom-built carburetor when you need a complete carburetor rather than a rebuild of one you send to us.

Tell us about your application

Share your vehicle, engine specifications, relevant modifications and intended use — stock, performance or race. Email info@quadrajetpower.com with your specifications or questions so we can recommend the appropriate build.

Check core and fitment requirements before ordering

We use a core from our inventory, typically one originally made for the same vehicle make. It may not be numbers-matching; fuel-inlet and throttle-arm arrangements may differ from the original. Ask first if you need a specific Quadrajet code. Availability and price can vary by the code requested.

Review our build process, levels and finish options, and check current turnaround times before ordering. Custom builds are made to order.

Already have a carburetor?

For our shop to rebuild your own Quadrajet, use the QB1 send-in rebuild service. For parts to do the work yourself, compare KitL1, KitL2 and KitL3 rebuild kits. Not sure which carburetor you have? Start with the identification guide.
