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.

Since you know who sold you the car, the easiest way to contact him through the board is ether a PM to start a conversation or you can give him a mention in this post like this;

@jacko241

This is now going to notify him he was mentioned in a post.
He was here on Friday.
