Question on what i should pay for a 1973-1974 dart sport

Im looking for some advice on what this 1973-1974 dart sport slant 6 is worth
This is going up for auction and was wondering what i should bid
It came from factory with hood scoops to look like the v8s but it came with a slant 6
Everything is original with very little rust, i thought maybe it would be worth more since it came with the scoops and strips from the dealer.
Isnt even worth putting in an offer?
Only have the one picture
