Do you know anything about this 383 Duster?

You are correct. We knew about this post since it is from the seller we bought the Duster from. We are seeking info about the history before the seller got the car. He did not assemble the engine, nor do any of the specific work regarding turning the car into a race car. I also want to clarify that we do not have buyers remorse, we are only curious about the Duster´s history and if available any e.t. numbers if drag raced.
