Review CARTER Thermoquad Carburetor Dodge Charger Hp 6320s Mopar fits CHALLENGER 400 1973

The Carter ThermoQuad 6320SA carburetor is a high-performance intake system solution for 1973 Dodge Charger and Challenger models with 400 hp engines. This carburetor is specifically designed to deliver optimal air/fuel mixtures for enhanced power and torque, making it an excellent choice for Mopar enthusiasts seeking superior engine performance.

The 6320SA ThermoQuad carburetor is a quad-barrel design, featuring four separate barrels that provide increased fuel delivery capabilities compared to a single or dual-barrel carburetor. This design not only offers improved engine response but also ensures that each cylinder receives the precise amount of fuel it needs, ultimately leading to a more balanced and efficient combustion process.

One of the most notable features of the Carter ThermoQuad 6320SA carburetor is its advanced thermal secondaries system. This system utilizes additional fuel jets located above the primary jets within each barrel. The secondary jets are thermostatically controlled, meaning they open when the engine temperature reaches optimal levels. By delivering additional fuel during high-load situations, the ThermoQuad system helps ensure that the engine maintains optimal power and performance, even under heavy acceleration or during high RPM operation.

Another essential aspect of the 6320SA ThermoQuad carburetor is its adjustability. Each barrel is individually adjustable, allowing fine-tuning of the air/fuel mixture for each cylinder bank. Additionally, the carburetor includes adjustable idle mixture screws, which can be used to set the engine idle speed and quality.

Constructed from high-quality materials, the Carter ThermoQuad 6320SA carburetor boasts a durable, long-lasting design. Its polished aluminum finish not only looks great but also helps to dissipate heat, ensuring consistent engine performance.

Installing the Carter ThermoQuad 6320SA carburetor on your 1973 Dodge Charger or Challenger with a 400 hp engine is a straightforward process. The carburetor comes complete with all necessary hardware, including mounting brackets, throttle linkage, and intake manifold gaskets. This makes for a hassle-free installation process, allowing you to enjoy the benefits of this high-performance intake system as soon as possible.

In conclusion, the Carter ThermoQuad 6320SA carburetor is an exceptional choice for 1973 Dodge Charger and Challenger owners with 400 hp engines seeking improved engine performance. Its advanced quad-barrel design, thermal secondaries system, and adjustability make it an ideal solution for delivering optimal air/fuel mixtures and enhanced power output. With its durable construction and straightforward installation process, the Carter ThermoQuad 6320SA carburetor is an essential upgrade for any Mopar enthusiast.
