Not that this is worth anything, but I had 2 April 72 Mach 1's. At the same time as well! One was a Q code, the other an H code. Neither had ram air. The Q code unfortunately did not have the original block and when I got it. It did not even have an air cleaner, so I made one at work with dual snorkels. There was no evidence of ram air ever been on it and it did not have hood twist locks as well.
I notice the pic you show, that car does not have twist locks. I thought that with Ram Air came hood locks as well. The need for hood locks was to hold the ram air air cleaner lid down on the seal.
EDIT: Just for sh*ts and giggles, here's the pic of the air cleaner I made for the Q code car.
