L67 gen 3 supercharger off of a 2000 Buick Regal with only 88k miles!! Excellent working condition. It has a zzp performance modular pulley hub already installed! ( cost $100 plus labor to install) included is a 3.6 pulley. You can easily change sizes by removing 5 simple Allen key bolts! This listing also includes all mounting bolts and the bypass valve and vacuum tree as shown in the pics. I also have the lower intake manifold available ( separate listing) and a zzp ported throttle body with phenolic spacer ( separate listing) among other l67 parts. This supercharger will fit any 3800 series 2 engine
