5.0 / 5.8 Summit Racing Blue Annodized Under Drive Pulley kit
I have a complete under drive pulley kit from Summit Racing. It is used (about 6 months old) but is in very good shape. It consists of a Crank Pulley, Water Pump Pulley and a Alternator Pulley. The Alternator pulley has been modified to work with a keyed alternator shaft so in the grinding some of the blue annodizing was grinded off. Paid about $120 new.. $50 + shipping. Will edit and post some pics later tonight.
Summit Part # is SUM-329700w
