None of these so ordered '71 HO Formulas were ordered with pwr disc brakes, P/S, or RA aircleaners, the RA aircleaners were heavy & owners figured that in. Instead, two of the such HO Formulas I've ran across ran just a deep drop 14" aircleaner base snugged down with carb return springs to the intake, this allowed smooth airflow into the Q-jet at the strip.

Not to take this off subject but a refresh of some NHRA history. The biggest reason these cars that were intended for dragracing (as many others) were ordered without their ram air setups is because without it the cars were automatically factored into a lower class. Those that were in the know, knew the fresh air wasn't a huge improvement in ET and it was much easier to factor the car in the lower class and run under the index.
Having collected a few different brands of "fresh air" cars myself I've run accross several R code mustangs that were missing their shakers. Owners would reinstall flat hoods to reclass the car, sometimes switching back and forth, and over the years these pieces get misplaced. Alot of people look at these cars today and can't comprehend why these expensive parts are missing. That's just what we did back in the day.

Very interesting! I was curious why my '71 455HO M22 was ordered as a stripper for racing but no Ram Air. Makes complete sense.
