So....it is an EV2 340 "promo" car. For whatever reason these cars weren't coded for the SHAKER hood, last minute change? Not surprisingly that '71 Challengers such as your car exist. Is it because of the cars "promo" status ("M" - VON?) that it doesn't have "N96" on the fender tag, as is the case for most of the "promo" GY3 440-6bbl '71 'Cudas (SHAKER & no "N96")?
