The Rochester Quadjet DTD 0970 carburetor is a legendary component of the 1970 Corvette, bringing power and performance to this iconic American sports car. This quad-barrel carburetor, specifically model number 7040505, was a crucial part of the Corvette's fuel delivery system during its third generation.

The Quadjet DTD 0970 carburetor features a unique design that sets it apart from other carburetors of its time.

Each venturi within the Quadjet DTD 0970 carburetor is topped with an individual throttle blade that is controlled by a single linkage. This design offers precise control over the engine's air-fuel mixture, allowing the driver to fine-tune the vehicle's response to their desired driving conditions.

The Rochester Quadjet DTD 0970 carburetor also incorporates a mechanical secondary system. This system, which is activated by a vacuum-operated butterfly valve, provides an additional fuel supply during wide-open throttle situations. This supplementary fuel improves the engine's power output and overall performance.

The Quadjet DTD 0970 carburetor is meticulously crafted from high-quality materials, ensuring durability and reliability. Its robust construction can withstand the rigors of high-performance driving, making it a popular choice among Corvette enthusiasts and collectors.

In summary, the Rochester Quadjet DTD 0970 carburetor is an essential component of the 1970 Corvette's fuel delivery system. Its unique quad-barrel design offers improved idle stability, smoother throttle response, and enhanced power output. With its precise control, durability, and legendary status among Corvette enthusiasts, this carburetor is a must-have for any serious Corvette collector or restorer.

Details:

There are no painted parts on this restored carburetor. Happy buying. This rare carburetor has been completely disassembled and boiled out. All of the hardware is then re-plated back to its original finish and carburetor assembled factory specifications using all new parts components.

E-mail us for details. The throttle shaft is line reamed and brass bushings are installed to eliminate that lean idle miss you get when the shafts loose. All of the main wells are epoxy coated. The carburetor is then acid etched like an original factory.
