I posted this auction about 2 weeks ago on LS1truck. Apparently he didnt sell the truck, so hes trying again. Hell no he is full of . They never made a factory supercharges SS. If they did, i would be driving one . It was most likely a dealership option. Now the dealership might have fed this guy a load of crap when he bought the truck. But all it is is a regular SS with an aftermarket supercharger.
