I don’t think it matters much over 318 or 383-2bbl originally if they’ve both been upgraded to 440 or same motor now.
These chargers have turned into blank canvas’ to make custom or slightly modified car of your choice.
The collectiblity is in the R/T. Or maybe something odd and desirable. Like an original sunroof car. This 383 N-code 4 speed in sublime might be worth keeping stock.
