A Stage 3 rebuild is intended for enthusiasts with serious street/strip, and dedicated race cars. A Stage 3 carburetor features an oversize (.135-inch) needle and seat assembly, and an increased main-well size that is balanced to assure sufficient top-end, high-RPM fuel flow. Finally, extensive circuit modifications are performed to keep the fuel curve correct throughout the entire RPM range to obtain instant, off-the-line response for consistent performance.
