You might not know this, but Mach 1 represents the speed of sound in a given medium. In air, the number is variable and it is dependent on the pressure and temperature of the air, composition of gasses, humidity and other things that will probably bore you if I take the time to explain them. Perhaps I’m underestimating you, and if so, please accept my apologies. What I mean to say is, I will probably bore myself learning about and explaining all of the variables involved in the calculation of this number. So what’s an author to do in this case?
Make something up.
Which is exactly what scientists did when they decided what the reference number for mach 1 would be. That is to say, they assumed fixed conditions. They assumed low humidity (whatever that may mean) but you could say it is the humidity found in the Phoenix area of Arizona, where a slice of bread left on the table for 10 minutes turns into a crouton.
Additionally, the temperature is assumed to be 68 degrees and at sea level. In other words, all of the fixed conditions of a good hair day. So given the conditions of having a good hair day at a crouton factory in the desert, the speed in MPH is 767…give or take. It depends on the flavor of croutons and what kind of shampoo you use.
It also depends on who is doing the talking. For example, if I were to tell you that you just won an all-expenses-paid Scotland scotch whiskey tour, interspersed with a round of golf at each of the top ten courses, followed by an all access pass to the Goodwood festival of speed. You’d hear what I am saying very quickly. Say, 1,203 miles per hour.
However if you find yourself at the business end of your spouse petitioning you insistently to get off your lazy ass and take care of the leaking toilet (because for God’s sake it’s been over a month) the speed of that particular sound rapidly approaches something resembling a walking toddler 2 weeks after learning how to stand upright.
Regardless of the appropriateness of the demand-request, the speed of sound is just a matter of physics that are impossible for us mere mortals to overcome. Oh well, we are all at it’s mercy, at least until today’s airing of the (insert-country-here) Grand Prix has finished.
Which brings us to the Mustang Mach I. Does the car go 767 mph? No. But the speed it goes is a lot closer to the free diving trip in Belize than handling the backed up septic system, if you catch my drift. And I suspect it’s a car that Chuck Yeager would approve of. (He’s the test pilot who was the first to break the sound barrier while flying what amounts to being a bomb with wings that someone could sit in.) BTW, Gen. Yeager just turned 96 this February, which is a testament to his skills as a pilot. Check out his bio some day. Let’s just say “badass” of the highest degree.
This red and black two-tone over black interior and has 67,000 original miles. The 351 bored engine with a 4-barrel Edelbrock carb has been rebuilt and the auto trans (FMX Cruise-O-Matic) was overhauled at the same time.
The original 2.75 rear axle comes with the sale of the car, but currently installed is a 3.25 posi. Dash has been redone and has been fitted with an 8 track AM/FM just in case you still have your Jefferson Airplane cassettes hanging around.
Tachometer has been replaced and a high throughput aluminum water pump and 3 row aluminum radiator has been installed. Electronic fuel pump with cutoff switch, power steering pump, chrome pulleys, new exhaust system with chrome exhaust tips, and shoulder belt.
Asking price for this clean and mean fastback rocket is $39,500. You can find out more info and contact the seller HERE on craigslist.
