A true blast form the past. These highly sought after superchargers have been unavailable for years. Weiand is proud to reintroduce them. The case of the 8-71 superchargers have been redesigned for a nostalgic look that will look at home on a cacklefest dragster as well as a new high end build. HORSEPOWER! - Weiand's 8-71 kits are the ultimate statement of power and looks. Pull into the local cruise-in or dragstrip with one of these sticking through the hood and you will get noticed. They're not for the meek however - these supercharger kits are designed to generate 50%+ more horsepower and torque across the rpm range! Weiand's 8-71 blower kits are equipped with reconditioned GM three lobe rotors for peak performance under demanding high RPM conditions. All feature a new case, end-plates, manifold and snout. Billet belt tensioner components and V-belt pulleys round out the package to give you everything necessary for installation. Kits are engineered 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. All 8-71 kits come with the extra tough 8mm belt configuration. Satin or polished finishes are available to match the "hard-core" or "show and go" look you're after. All superchargers are built in Weiand's state-of-the-art manufacturing cell and each supercharger is 100% boost tested to help you squeeze out maximum power and efficiency.

Features:

  • Long Nose
  • 3" Gilmer Drive Belt
  • 11.5% Underdriven Drive Ratio w/ Included Pulley Set
  • Satin Finish
  • Develop 550+ Horsepower out of a mild 454 Chevy
  • Instant, full-time power every time you hit the throttle
  • Substantially increases torque
