Review PLYMOUTH Dual Rear Carter Afb Carburetor 4971 fits HEMI QUAD CUDA GTX 1971

Introducing the Plymouth 4971S 1971 Hemi Dual Quad Rear Carter AFB Carburetor, a legendary component of the iconic 1971 Plymouth Hemi GTX and Cuda muscle cars. This carburetor is a testament to the power and performance that defined the muscle car era.

The Plymouth 4971S is a 4-barrel, dual-quad carburetor, meaning it consists of two 2-barrel carburetors mounted side by side. Each barrel features an Accelerator Flow Benchmark (AFB) design, which was an advanced technology for its time. The AFB design optimizes airflow and fuel mixture for maximum power and efficiency.

The 4971S carburetor is specifically designed for use with the Chrysler 426 Hemi engine, a powerhouse that delivers an impressive output of 425 horsepower and 490 lb-ft of torque. The carburetor's unique configuration, with two separate intakes feeding each bank of cylinders, ensures optimal fuel distribution for this high-performance engine.

The 4971S carburetor features a Carter YF-series base with a polished finish, adding a touch of elegance to the engine bay. The base is equipped with a vacuum secondary system, which enhances low-end torque and improves overall drivability.

Each barrel is outfitted with a mechanical secondaries system, which utilizes mechanical linkages to open the secondary throats when vacuum pressure reaches a certain level. This design ensures a smooth powerband and responsive acceleration.

The 4971S carburetor is also compatible with electronic ignition systems, making it a versatile choice for modern muscle car restorations and hot rods.

In summary, the Plymouth 4971S 1971 Hemi Dual Quad Rear Carter AFB Carburetor is a high-performance component that delivers power, efficiency, and style. Its advanced design, dual-quad configuration, and compatibility with modern technologies make it a sought-after addition for any muscle car enthusiast or restoration project.

Details:

I removed the top plate to inspect inside and it looked good with no corrosion. This is missing some common small parts than can be had from other AFB's. All parts move as they should with nothing being stuck. Hard to find part for your early Dodge or Plymouth.
