Brand New Holley Quick Fuel Slayer Series Dual Tunnel Ram Carburetors, Front & Rear, 450CFM, VS (Part #SL-450-VSTRF & SL-450-VSTRR).

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. 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.

Notes: 

• This model of carburetor has the square bore flange bolt pattern. It can replace Holley, Edelbrock, Carter AFB, and Autolite style carburetors with 5 3/16" x 5 5/8" bolt pattern.
