GM Big Block Weiand 6-71 Supercharger Kit - Polished 7583P

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 6-71 and 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 6-71 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 6-71 blower kits are equipped with exclusive two lobe rotors for maximum boost at lower RPMs. 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 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.
