Small roots blower for smallblock

Pretty cool. These little things are sweet. I have a NOS B&M kit I haven't got around to yet. Ditch that 6 rib pulley Pos ASAP and go straight to 10 rib...if you can that is. Since no one ever made a 10 rib crank pulley for the SBM, I had one designed after the one in my kit, took months for my friend to machine it for me. LOL. I then bought a new blower snout 1" shorter, available through Weiand, again, those aren't cheap. The extra 4 ribs in the pulley was exactly 1" so I got lucky with that!
