This carburetor is part of Holley's Ultra series, which offers improved idle stability, vacuum secondary, and power valve design for optimal engine performance.

The rods are also treated with a special nitriding process, which further enhances their strength and resistance to pitting and scuffing. The rod tips are precision-machined to ensure a perfect fit and sealing surface with the associated carburetor components.
This Holley R7667A 2-barrel carburetor and R7667 rod ratio are suitable for various applications, including late-model Ford, Chevrolet, and Mopar engines. By upgrading to this high-performance carburetor and rod ratio, engine builders and enthusiasts can expect improved throttle response, increased power output, and enhanced drivability. Additionally, this carburetor is compatible with Holley's Electronic Fuel Injection (EFI) systems, allowing for the possibility of a hybrid fuel delivery system for even greater performance and efficiency.
In summary, the Holley R7667A 2-barrel carburetor, with the R7667 rod ratio, is a high-quality, performance-oriented component specifically engineered for automotive applications.
