Carburetor Main Body - 950CFM

The PROFORM Carburetor Main Body 950 CFM (part number 67108C) is a precision-engineered conversion component designed to transform a street carburetor into a high-flow performance carb. Built from aluminum and finished in natural, this main body assembly integrates seamlessly with Holley 950 CFM carburetor platforms, enabling enthusiasts to upgrade their fuel delivery systems for improved throttle response and increased fuel atomization across the RPM band.

The 950 CFM flow rating represents a substantial increase over stock street carburetor capacities, making this main body suitable for mid-range to high-displacement engines seeking performance gains without sacrificing driveability. The aluminum construction provides both weight savings and thermal stability, reducing heat soak that can degrade fuel atomization during sustained acceleration or towing. Weighing 3.19 lbs with compact dimensions of 5.9 x 5.6 x 5.95 inches, this component maintains a low-profile package that fits within space-constrained engine bays while delivering the increased air and fuel delivery capability modern performance builds demand.

This main body assembly targets street rod builders, classic car restoration projects, and performance enthusiasts converting older Holley carb platforms to higher-flow specifications. The conversion approach allows builders to leverage existing fuel line routing and linkage compatibility while upgrading core metering circuits and air passages. Installation requires matching this main body with compatible Holley 950 CFM internals and fuel delivery components to establish a complete, balanced carburetor system tuned for the intended engine combination.

The 950 CFM specification positions this carburetor in the performance tier suitable for engines from 400 to 550 cubic inches, depending on camshaft profile, intake design, and intended RPM range. Builders selecting this main body should verify compatibility with their fuel pump capacity, fuel line sizing, and intake manifold vacuum requirements to ensure the conversion delivers the targeted performance outcome without lean-running conditions or flooding issues.
