So I am considering buying a buddies 1971 Demon. It’s on original triple f7 H code car with the original white side and rear stripe. It has the original 340 motor, but has a 727 instead of the a904. Body is clean, interior is beat up, defiantly needs a repaint. Would I kill the value and history of the car to change the color? I was thinking Green Go or Sublime green. Not many H code cars that I see for sale anymore but I just never liked f7.
