History of Ford Mustang : Third Generation (1969-1970)

The Mustang got larger once again for 1969 even though the wheelbase remained 108 inches. The new body for 1969 featured four headlights, a sharp nose with a simpler grille that dispensed with the famed running horse centerpiece and a revision of the fake side scoops on the coupe and convertible. The fastback had large nonfunctional scoops dug high into its rear fenders. Unlike the '67, the '69 design clearly broke from established Mustang styling themes.
But under the sheet metal the Mustang still carried that Falcon-sourced front suspension and the solid rear axle was still perched on leaf springs.
The range of powertrain options grew once again for '69 and those led to the development of exciting new models. Base power still came from the 200-cubic-inch straight six, the 250 six was back again as an option. But the 289 V8s were gone for good with a two-barrel, 220-horsepower 302 now serving as the least intimidating V8 available. Beyond the 302 was a new 351-cubic-inch (5.8-liter) V8 which made 250 horsepower when gasping in air through a two-barrel carb and 290 horsepower with a higher-compression ratio and four-barrel carburetion. The 390 was back making 320 horsepower and two 428s were offered, with the "Cobra Jet" version making 335 horsepower and the "Super Cobra Jet" pounding out 360.For those who wanted a luxurious Mustang, Ford offered the '69 coupe as a "Grande" model.
For those who wanted a performance image, the company came up with a "Mach 1" version of the 2+2 fastback available only with the 351, 390 or 428 engines.
The two most intriguing '69 Mustangs came in the middle of the model run. Both were named "Boss" and both were built for racing.
The Boss 302 Mustang arose because Ford needed a car to go up against the successful Camaro Z28 in the SCCA Trans Am road racing series. So Ford came up with the Boss 302, which benefited from an optimized suspension, a neat Larry Shinoda-designed body package (which included a flat-black hood, rear window louvers and a rear deck spoiler) and a high-compression, deep-breathing 302 V8 making a wicked 290 horsepower. Ford would sell 1,628 of these near-racers and they'd prove effective weapons on the racetrack as well.
The Boss 429 was built only to homologate Ford's spectacular 429-cubic-inch (7.0-liter) hemi-headed V8 for NASCAR stock car competition. The 429 was ludicrously underrated at 375 horsepower (500 horsepower was more like it), and there's no explanation as to why the company insisted on shoehorning the big engine into the Mustang (the front suspension had to be virtually redesigned) instead of putting it in the roomier bay of the Torino, which was the car Ford actually ran in NASCAR. Only 859 Boss 429 fastbacks were built during the '69 model year and they all had large functional scoops on their hoods.
Those Boss 429s were but a drop in the 1969 Mustang sales bucket. In all, Ford sold 299,824 Mustangs that year, including 72,458 Mach 1s and 14,746 convertibles.
Ford went back to just two headlights for the 1970 Mustang, replacing the outboard lights with attractive scoops that fed nothing at all. Other changes included the elimination of the phony side scoops from all models. Also, the 351 V8s now came from Ford's Cleveland plant and were of a slightly different design from the previous 351s that had been built at the Windsor, Ontario, facility.
During the '70 model year, sales dropped to 190,727 Mustangs including 6,318 Boss 302s, 499 Boss 429s and just 7,673 convertibles.
