Just depends on what route you wanna go and how much money you want to spend. You can get an iron block 6.0 from a salvage yard from a 2500hd truck, then switch over all your goodies from the tbss to it. Have one built from a reputable shop to your liking. Or buy a stock short block, then put heads intake and accessories from the truck on the new short block. Blueprint engines and Texas speed are just a couple of places that offer short blocks to complete engines. Best of luck
