Is a 1967 440 HP Engine in a Chrysler automatically a TNT?

Found a parts car in the Interior of the Province, 1967 Chrysler 300, has the 440 with the HP on the pad, but does not have the HP manifolds, or other tell tale signs of being a TNT car. Perhaps the manifolds and air cleaner etc were replaced, but wondering if this is realistic? Trying to get the Seller to shovel the snow off of it to give me the VIN # but he is elderly and reluctant to do this. CG
