I ordered the power steering pump brackets for the 454 Friday and while I was there I asked about the PS pump. According to the computer at the dealership the big block pump is different from the small block (at least the part number is). So my question is, will I be able to use the small block pump on the big block?? Or maybe it's just the pulley that differs? If so, anyone know of a place to get a cheap PS Pump pulley for the big block setup? Big time thanks! If it doesn't sit on a frame, then it isn't a truck.
