I have used every kind of detailer on the ole Mach1 until I found DualPolymer. It cleans the dust and will bring a shine you have never see. Check it out at www.dualpolymer.com and use my code "porboy" for a 20% discount.
The '69 Mach 1 also debuted with raging success. The Mustang fastback had evolved into a super slippery fastback body. Some say that there has never been a better looking Mustang fastback in the marquee's history. Ford splashed striking graphics on the Mach 1--color-keyed side stripes, matte-black hood striping, hood pins, sidescoops, chin and deck lid spoilers, sports slats to keep the sun out and the cool in, and twin-set headlamps. it was an ultra sharky facade few car buyers could resist.
The Mach 1 came standard with a 351W-2V V-8. For those wanting optimum performance, the car was also available with a 428 Super Cobra Jet sporting Ram Air and a Drag Pack. Choices were many. Most '69 Mach 1s rolled off assembly lines in San Jose, Dearborn, and Metuchen with 351W two-barrel and four-barrel V-8s backed by FMX cast-iron automatic transmissions. The 351W Mach was a snappy Mustang SportsRoof for the average guy who wanted terrific looks with a sprinkling of muscle.
The beauty of the Mach 1 was that it could be ordered hundreds of different ways. The choices included 16 exterior colors, three interior colors in knitted vinyl, five transmissions, 10 axle types, six engines, and dozens of options--including cruise control. There hasn't been a Mustang this generously optioned since. At base sticker price, the Mach 1's 351W-2V V-8 yielded 250 horsepower backed by a fully synchronized three-speed Top Loader transmission and a 3.00:1 conventional 9-inch axle. Inside, the base Mach 1 was generously equipped with a standard Knitted Vinyl Sports Interior, high-back bucket seats, a console, pod-style instrumentation, an AM radio, and molded door panels.
On the ground were styled steel wheels clad in chrome with spun center caps. Color-keyed styled steel wheels also were available, but they are a rare find today. These wheels were wrapped in Firestone Wide-Oval belted F70x14 tires. With the rolling stock came the Competition Suspension with stiffer spring rates, shocks with revised valving, a heavy-duty front sway bar, and 16:1 steering. New for '69 was the optional shaker hoodscoop actually mounted atop the air cleaner housing. Inside the shaker was a vacuum-actuated air door designed to open to the slip stream at wide-open throttle. No one has ever been able to prove if the shaker gives a Cobra Jet any more power, however. But it carries plenty of emotional firepower just the same.
The '69 Mach 1 deeply pocketed twin-set headlamps and mouthy grille spoke "Mustang" in every respect when it was introduced in the fall of 1968. It also proved to the masses that the Mustang had matured to become a world-class touring car. It was a cut above the original '65 Mustang in terms of comfort, handling, and performance. The Mach could hold its own against the competition in any theater. Racing veteran Mickey Thompson flogged a couple of specially prepared Mach 1s at the Bonneville Salt Flats in some of the heaviest endurance testing ever performed on a production automobile. The Mustang had swiftly become a cultural icon.
While most of us like the small-block Mach 1, even more are thrilled with the power of a big-block. The most common Mach 1 big-block was the 428 Cobra Jet sporting 335 horsepower. However, did you know the rarest '69 Mach 1 isn't Cobra Jet-equipped? Surprisingly, it's the docile 390 High Performance V-8, yielding 320 ponies. The 390 Hi-Po Mach 1 is rare because the cost to get into a Cobra Jet wasn't that much more.
Controlling that power were optional front disc brakes. Believe it or not, the Mach 1 came standard with manual four-wheel drum brakes, including Cobra Jet models. The Competition Suspension was standard equipment. For a few bucks more, Cobra Jet buyers could find themselves in the middle of the Drag Pack option. With Drag Pack, your Mach 1 was fitted with either 3.91:1 or 4.30:1 Traction Lok, staggered rear shocks (four-speed only), an engine oil cooler, and the beefier 428 Super Cobra Jet engine. The Super Cobra Jet didn't make any more power than the standard Cobra Jet, it was simply better prepared for weekend racing with heavier Le Mans cap-screw connecting rods and a better crankshaft.
Some information I have found on the Mach1 if you have more or better send it to Loren. During 1967-'68, Ford introduced a short-lived concept Mustang called the Mach 1. It was a slippery '67 fastback-based styling exercise shown around the country at new car shows, in car magazines, and at National Council of Mustang Club round-ups. The Mach 1 was a huge success--so much so that Ford would assign the name to the all-new Mustang SportsRoof body for 1969.
