This carburetor, specifically identified by the BLHN 1450192, is a direct replacement for your factory setup, providing improved throttle response, idle stability, and fuel efficiency.

1. Adjustable secondary throttle plates: Offering precise tuning capabilities, these plates allow you to fine-tune the secondary fuel mixture for optimal power delivery.

2. Adjustable idle mixture screws: Located on both primary and secondary venturis, these screws enable you to dial in the ideal idle mixture, ensuring stable idling under various conditions.

3. Adjustable primary and secondary idle jet: Providing the ability to fine-tune the idle jet's size, you can easily configure this carburetor for your specific engine setup and fuel requirements.

4. Built-in fuel pressure regulator: Eliminating the need for an external regulator, this carburetor comes with a built-in regulator that simplifies the installation process and reduces potential fuel pressure issues.

5. 4-corner adjustments: With adjustable primary and secondary idle mixture screws, along with primary and secondary throttle stop screws, you can easily fine-tune your engine's idle characteristics for optimal performance.

Constructed from premium materials, the Holley 64-7283 GM Dual-Port 210 CFM Carburetor is built to withstand the rigors of high-performance applications. Its robust design ensures long-lasting durability, allowing you to enjoy consistent engine performance for years to come.
