The Holley XP Replacement Main Body 950 CFM HC Gray is a premium carburetor main body assembly designed for high-performance street and competition applications. This aluminum hard core gray replacement body delivers the flow capacity and precision tuning control that experienced builders demand when upgrading or rebuilding Holley Ultra XP carburetor systems. At 950 CFM, this main body strikes the balance between adequate fuel and air delivery for mid-to-large displacement engines without oversizing the carburetor for responsive driveability.
The 950 CFM specification reflects the carburetor's air-handling capability under standard conditions, making it well-suited for naturally aspirated engines in the 350–500 cubic inch range with moderate to aggressive cam profiles. The aluminum construction provides excellent thermal properties and reduces weight compared to cast iron alternatives. Hard core gray finishing offers both corrosion resistance and a professional appearance in engine bays where heat and fuel exposure are constant. Builders selecting a 950 CFM main body typically pair it with matched fuel bowls, metering blocks, and jets to achieve their target air-fuel ratio across the RPM band.
This replacement main body is engineered for restorers, performance tuners, and weekend racers who need a direct-fit Holley Ultra XP component that maintains OEM precision tolerances. Whether you're rebuilding a carburetor that has seen extensive use, upgrading from a smaller CFM rating, or establishing a baseline platform for custom tuning, this main body provides the foundation for consistent jetting, air bleed optimization, and fuel delivery control. The hard core gray finish integrates seamlessly into custom and classic engine builds where aesthetic detail matters alongside performance.
