It is the correct engine for my truck and no one can tell it isn't the one it left the factory with

You are correct as long as the truck build date was after the build date of the engine. In 1972 they were still using leftover 71 motors for a while. So as long as the application is correct there is no way of telling As far as correct motor for this truck this could still be the original 283. At any rate nice find mike it will make someone a nice project. Well worth investing money into
