Hood Snorkel or not to Hood Snorkel

This forum has been invaluable in helping me work through the collection of A bodies my Dad had squirreled away over the years, so thank you in advance. The next question I have while trying to unlock Mopar mystery is did all '73 Dart Sport 340's come equipped with hood snorkels? I have a '73 340 that I believe to be all original other than someone changed paint from black to red but it doesn't have the infamous snorkels. Please offer some insight.
