The 454 in my k30 has the prefix CFS followed by the vin that matches the truck. I can't find CFS anywhere on the internet. Can someone help? The reason I ask is because I have the truck for sale locally and a buyer thinks the truck was originally an automatic instead of the 4 speed that's in it now. I'm not sure and I need to know what I'm selling. Thanks!
