Combining the years of experience with tunnel ram and dual carburetor applications, Quick Fuel has developed a matched carburetor pair based on the 450 Slayer series for your tunnel ram application. The front carburetor is a no choke model calibrated to work with the rear carburetor for the performance that you are looking for. Purchase the SL-450-VSTRF (front) along with the SL-450-VSTRR (rear) for the matched performance for your dual carburetor application. Slayer Series street carburetors are designed with many of the same innovations and features that are built into all QFT™ race-winning carburetors, including changeable air bleeds and power valve channel restrictions. It's designed with a secondary metering plate with changeable jets, and features all aluminum components for additional weight savings. All Slayer Series carburetors are equipped with universal throttle levers to accommodate Ford A/T kickdown, GM 700 R4 mounting holes, and ability to mount brackets for Chrysler vehicles. Slayer Series are available in 450, 600, and 750 cfm vacuum secondary models. • Vacuum Secondaries • Electric Choke • Single Metering Block • Secondary Metering Plate • Cast Aluminum Throttle Body • Single Sight Glass Windows • Changeable Air Bleeds • Adjustable Needles & Seats
