QFT has solved this dilemma with three new 450cfm models centered around a single die-cast aluminum main body with 1.090” venturis and 1-9/16” throttle plates. There is a mechanical secondary HR-Series, a polished vacuum secondary Slayer model and a Black Diamond® version of the Slayer. These carbs feature normal 4150 modular carb dimensions such as air-horn diameter and baseplate bolt pattern – so they bolt to 4150-flanged intake manifolds and accept traditional four-barrel air cleaners.
QFT’s HR-450 model shows its true performance heritage with mechanical secondaries, dual metering blocks and dual-inlet fuel bowls. The only visible concession to daily street driving is the electric choke. Enthusiasts are already sizing up these carbs as ideal for small-block street tunnel rams. Install the 1:1 Quick-Link™ secondary link for cruise night antics, then swap back to the 40% link for more economical daily driving.
The Slayer SL-450-VS and BD-450-VS offer all of the adjustability of the original Slayer carb and feature the single-inlet, side-hung fuel bowls that make them so adaptable to early muscle cars and O.E. replacements. They both have vacuum secondaries with QFT’s Quick-Set™ single screw adjustment and electric chokes. They are completely adjustable with changeable air bleeds and primary and secondary main jets. The Black Diamond® version lowers fuel temperatures by up to 6% and is scratch and corrosion resistant.
