1971 Demon Snorkel hood??

Looks like I have a 71 340 Demon with a snorkel hood and hood pins option. It looks far to original I think not to be a part of this car. Its an EV2 color and all under the hood is still in the original paint. Maybe it was a late 71. I was planning on doing a rest but might end up selling it to do another Duster I found with the V24 hood option.
