As you can see from the date of the original post, this debate has been ongoing for a while. At the dealership, we have heard Mach1 hood, Ram air hood, NASA or NACA hood. The '71 car facts salesman organizer states that under standard exterior equipment, the Boss 351 includes a NASA-type hood with functional hood scoops. The Mach1 is listed as having a unique hood with twin NASA-type hood scoops. The '71 Spring Special Value package content lists the NASA Hood as included.
The Ram Air option states that it includes a functional Mach 1 hood. A no-charge option was listed for the NASA-type hood for the 302-equipped Mach1.
For '72, not much had changed. The Mach1 was still listed as including a unique hood with twin NASA-type hood scoops, which was still listed as a no-charge option for the 302-equipped Mach1 only. The Ram Air option once again was listed as including a functional NASA-type hood, which, as of 1/72, was only available with the 351 2V engine. For the '72 Sprint Mustang, the information I have specifically stated that the NASA hood is not available as an option.
For '73, the Mach1 was listed as including a unique hood with twin NASA-type non-functioning hood scoops. The NASA hood was again listed as a no-charge option on the Mach1 with the standard 302 engine. The Ram Air option included a NASA-type hood and was only available on the 351 2V engine.
There was a new '73 option, "Tu-Tone Hood Paint." It included the NASA-type hood with black or Argent accent paint and twist-style hood locks. It had the look of a Ram Air-style hood but was non-functional.
The '65-72 and '73-79 Master Parts Catalog (MPC) only listed the hoods as W or W/O hood scoops.
Since mrgmhale is out of town and unable to access his window sticker (the Monroney label), I will post one for a '71 Mach1 in my fleet (Money Pit #2) that only lists the hood as NASA-type hood scoops.
As you can see, Ford was inconsistent in their description of the hood, although they stayed with the NASA name. So, 50+ years later, call it what you want; we know what you mean! I got used to all the different names I heard it called.
