    Chevy Small Block Carbureted Supercharger Kits

    Fits: Universal Small-Block Chevy with Carburetor

    GM small-block carbureted blow-through system features the V-3 Si-trim supercharger with internal lubrication. This kit also includes the new Forcepower Hat. This unique cast aluminum piece features an internal diffuser for air control that reduces jetting related issues associated with a traditional carb hat. This design permits 360-deg rotation for universal fit. It has a low-profile height of only 3.2" with a 3" diameter inlet port. It includes a sealing gasket and all necessary hardware for use with a 4150 style carburetor. Adds up to 125HP at modest boost levels. Fits under the stock hood of most vehicles. Easily upgradable with various pulleys. Allows for V-belt or serpentine accessory drive configurations. V-3 compressor is capable of supporting up to 775 HP.


  • V-3 Si-Trim supercharger
  • Supplied pulley ratio will produce approximately 7-9 psi at 5500 rpm on a mildly modified 350" engine
  • Cast aluminum base mounting bracket with all necessary hardware
  • 3/8" thick nickel plated steel mounting plate for rigid supercharger attachment
  • Supercharger air inlet filter
  • Mandrel bent aluminum discharge tube with clamps and silicone sleeves
  • Cast aluminum carburetor bonnet assembly

    Each Vortech Supercharging System is developed to operate as a seamless addition to the base vehicle. By employing the same methods as original manufacturers, Vortech engineers create integrated supercharger systems that appear as if they're original equipment yet operate at an even higher level of sophistication. The boost curve generated by Vortech Superchargers is ideally matched with today's highly evolved engines and provides a power-when-you-need-it sensation. The supercharger and its subsystems fully integrate into the vehicle's existing platform, yielding a smooth continuity of power and performance.
