Dominator Flange Gasket 1350-1475CFM Open Style

The Dominator Flange Gasket 1350-1475CFM Open Style is a precision carburetor base plate gasket engineered for high-performance four-barrel carburetors in the Dominator series. Built for serious engine builders and performance enthusiasts, this gasket seals the critical interface between your carburetor's base flange and intake manifold, preventing fuel and air leaks that compromise throttle response and combustion efficiency. Whether you're tuning a street machine, bracket racing build, or naturally aspirated engine platform, a quality base plate gasket is non-negotiable for reliable carburetor operation.

Manufactured from composite material and precision-cut to 0.063 inches thick, the Dominator Flange Gasket accommodates the exacting tolerances of high-CFM carburetors rated between 1350 and 1475 cubic feet per minute. The open-style design allows full visibility and access to mounting holes during installation, reducing assembly time and installation errors. Holley's composite construction resists fuel degradation, thermal cycling, and compression set far better than traditional cork or paper gaskets, maintaining a reliable seal across thousands of heat cycles. The gasket's dimensional stability ensures consistent sealing without requiring repeated re-torquing, which is critical in competition or street environments where vibration and thermal stress are constant factors.

This gasket is essential for anyone rebuilding, upgrading, or diagnosing fuel delivery problems on a Dominator carburetor installation. Direct fit compatibility with 1350–1475 CFM Dominator models makes it ideal for both restoration projects and high-performance engine swaps where fuel system integrity is non-negotiable. Installation is straightforward: clean both the carburetor flange and intake manifold surfaces to bare metal, position the gasket, and torque the carburetor mounting bolts to specification in a crisscross pattern. Keep a spare on hand for troubleshooting lean conditions, fuel seepage, or routine maintenance intervals.
