Up for sale are 2 well used Detroit diesel allison 6-71 superchargers. They are not complete but I have a bag that has parts to complete them. Up for sale is a Holley 750 carburetor. Has a rebuild kit on it. Still worked great. Next is a Edelbrock Performer 460 intake manifold. Reasonbly lighter than stock. Next is a MSD Boost timing master. Never really had a use for it. Used with turbod or supercharged cars/trucks. Dont have the instructions. Also have a complete set of 289-302 head bolts. Washers are still in sealed packages. Brand new. Never used. Take a look and shoot some prices. The bluish supercharger is the one that has the parts.
