Quick Fuel Technology has several choices of 600 cfm performance carburetors for buyers to choose from. Yet none of these options provide engine builders with a single fuel inlet and side-hung fuel bowl. That’s why QFT has provided this new carb for its Black Diamond series, giving it the lineup’s trademark high-temperature coating and fully-adjustable electric choke. 

Official Release:

Quick Fuel Technology (QFT) produces several versions of 600 cfm performance carbs from the Hot Rod Series to the affordable Slayer™ Series. However, none of QFT’s current carburetors address the direct replacement requirements, including a single fuel inlet and side-hung fuel bowls. Quick Fuel’s newest carburetor, Part # BD-1957, addresses these issues, plus is packed full of QFT’s exclusive features such as QuickSet vacuum secondaries, Black Diamond high temperature coating and a fully adjustable electric choke.

QFT’s BD-1957 was designed as a street performance carb that is also suitable for stock engines. It flows 600 cfm through 1 9/16-inch throttle bores and 1.312-inch venturis. The BD-1957 has a secondary metering plate with changeable jets and 3-stage emulsion circuits. The Black Diamond coating reduces fuel temperatures by up to 6% and is extremely scratch and corrosion resistant. This proprietary coating keeps your carb looking factory fresh for years, even under harsh environmental conditions. A billet aluminum primary metering block and throttle body provides added strength, precise metering and zero porosity.

Quick Fuel makes carb tuning and setup very simple with its QuickSet vacuum secondary housing that allows you to adjust the secondary opening rate with a simple screw adjustment, instead of removing the housing cover and swapping springs. As with all Quick Fuel carbs, interchangeable bleeds allow you to fine tune both the idle and high speed circuits. QFT’s fully adjustable choke requires a simple one-wire hookup and you are ready to go. All BD-1957 carbs come with Ford A/T kickdown linkage included.

• Gives street performance qualities to your stock engine
