Curious if someone would have the part number for the GM Performance Parts Serpentine kit that will allow the use of a Vortech Supercharger on a blow through carb application on a '78 big Block for my '84 Square body. Speaking to a Vortech rep, he indicated that GM has a kit that allows their supercharger to bolt directly to it, but he couldn't readily put his fingers on it. The other potential option is to go with American Billet which also has a kit, but I would like to investigate the one offered by GM, but not having much luck finding it. Hoping someone has some experience with it....
