3 V-groove billet aluminum crank/balancer pulley for 142, 144, 174, and 177 Holley, B&M, and Weiand Blowers. I think it fits 250, 256, and 420 blowers with serpentine style belts also. Bought this new last year for $240 at Summit. It looks new, the black anodizing isn't even worn off by the belts. Part number is 155250. would make a nice pulley even without a supercharger. I sold my B&M blower to a guy for an automotive application and no longer need it. Like to get $100 + the ride.
