Description

The Quick Fuel Technology Slayer Series carburetor is a 450 CFM, 4-barrel vacuum secondary street carburetor specifically engineered to be paired with its counterpart for tunnel ram and dual carburetor applications. It is designed to work in tandem with the SL-450-VSTRF front carburetor to provide consistent, matched performance for street rod setups. The unit features all-aluminum construction with a polished body for improved weight reduction and thermal efficiency. Technically, this carburetor utilizes a square bore flange and incorporates race-derived innovations such as changeable air bleeds and power valve channel restrictions. It is equipped with a single metering block and a secondary metering plate that allows for jet changes. Universal throttle levers are included, providing compatibility for Ford A/T kickdown, GM 700 R4 mounting holes, and brackets for Chrysler vehicles. The setup includes a single sight glass window for easy monitoring and adjustable needles and seats. Installation of this carburetor is compatible with square bore intake manifolds. For users currently operating with a spreadbore style intake manifold, an adapter is required to ensure proper fitment. This component is strictly for use on uncontrolled, non-emissions controlled vehicles. It is illegal to install this part on any emissions-controlled vehicle, including 1966 and newer U.S.-manufactured California-certified vehicles, as well as 1968 and newer U.S. Federally-certified or foreign-manufactured vehicles.
