142 Powercharger Kit w/ 6-Rib Serpentine Pulley

The Weiand 6543-1 Powercharger Kit is a supercharger system engineered to deliver a substantial power increase, typically ranging from 25% to 40%, for Chevy small block engines. This polished 142 series supercharger features a long nose design and utilizes a 6-rib serpentine pulley drive system for seamless integration. Designed specifically for compatibility with Vortec or Fast Burn heads, this kit is built for stock/OEM standard engine blocks. It accommodates a single carburetor and does not include a damper. The Weiand Pro-Street Powercharger is engineered not only for performance gains but also to maintain outstanding streetability. Installation notes indicate that for blower kits like the 6543-1, proper intake manifold torque is crucial to prevent gasket damage. It is important to note that this kit will not fit 1992 or later LT1 engines. Specific fitment information suggests compatibility with Chevy small block Gen I 262-400ci V8 engines when equipped with Vortec or Fast Burn heads.
