    6-71 Superchargers - Chevrolet Big Block

  • 34 Tooth Lower Pulley
  • 38 Tooth Upper Pulley

    Note: This kit includes two extra 1/8" NPT plugs. Your manifold may have two 1/8" NPT ports tapped in the back of it. These are vacuum / boost ports that can be used for a boost gauge, boost reference power valves, or any other items that need to be connected to a boost / vacuum source. If these ports are not needed, use the included plugs to block these ports.

    More than 40 Years in the Supercharger Business

    Weiand superchargers can be found in all aspects of racing, from tractor pulls to the quarter mile. When you pull into your local cruise-in or dragstrip with one of these 6-71 superchargers sticking through the hood you are sure to be noticed. Producing 50%+ more horsepower and torque, the 6-71 supercharger is not just your average supercharger!

    All 6-71 kits are available with either the traditional 1/2" pitch (one piece snout) or the extra tough 8mm belt configurations to suit your needs.

    Got a HEMI? Weiand has nostalgic supercharger kits for early Chrysler Hemi's (331, 354 or 392). Hemi kits have the traditional 1/2" pitch drive and early one piece snout.

    Supercharger Features:
  • Roots-type two-lobe helical rotor eliminates flex
  • Rotor setup closes tolerances for maximum boost efficiency
  • Equal distribution of fuel/air mixture optimizes HP gains
  • Mounts with standard distributor setup
  • Heavy-duty bearing plates eliminate cracking
  • Rear plates use premium sealed ball bearings
  • Front bearings lubricated by oil bath
  • Front rotor shaft seals are double-lipped with PTFE
  • Kits are designed to produce 10-12 lbs of boost on small blocks and 5-7 lbs of boost on big blocks but are a simple pulley change away from pump gas or hard core racing.

    6-71 Street Supercharger Kits Include:
  • Polished or Satin 6-71 Supercharger with gears and bearing plates
  • Supercharger Intake Manifold
  • 2-4V Carburetor Adapter
  • Supercharger to Manifold Gasket
  • Carburetor Adapter to Supercharger Gasket
  • 3" Gilmer Belt, pulleys, brackets, idler, and necessary fasteners

    Note: Kits do not allow enough clearance to fit a GM HEI distributor. Fuel lines not included.
