Ford Mustang 1973 Mach 1

This 1973 Ford Mustang Mach 1 and its 351 Cleveland V8 mark the closing chapter of the original pony car generation — Ford built fewer Mach 1s this year than any other. Its cassette radio, tilt wheel, and raised-white-letter tires were the everyday extras buyers chose while, unknowingly, driving out the first-generation Mustang for good. Here’s what made the final year’s V8 lineup different.

This 1973 Ford Mach 1 is powered by a 351 Cleveland V8 engine with 2v Heads, backed by a FMX 3-speed automatic transmission, running to a Ford 9″ rear end with 2:73 gears.. Options include AM/FM Radio with Cassette, Power Brakes, Power Steering, Tilt Wheel, Seat Belts, Vinyl Interior, and Raised White Letter Radial Tires…

Every Mach 1 that rolled off the line in 1973 carried a quiet distinction that nobody buying one at the time would have understood. This particular car, with its 351 Cleveland V8, FMX automatic, and long options list of comfort features, represented the final chapter of a story that began five years earlier. Ford was about to close the book on the first-generation Mustang entirely, and this was the smallest print run of Mach 1s the company would ever produce. Buyers loading up on cassette radios and tilt wheels had no idea they were driving the end of an era. What made 1973 different from every Mach 1 year before it?

The Last of the First Generation

The Mach 1 package launched in August 1968 for the 1969 model year and would go on to run through 1978, but 1973 held a unique and somewhat unglamorous distinction: it was the final year of the original first-generation Mustang platform, and Ford built fewer Mach 1s in 1973 than in any other year of the option’s run. The Mach 1 package itself brought a NASA-style hood, honeycomb grille, blackout trim, dual color-keyed racing mirrors, front disc brakes, and a firmer competition suspension.

Two Versions of the Same V8

Under the hood, the 351 Cleveland came in two distinct states of tune for 1973. The two-barrel version, like the one in this car, produced 177 horsepower and 284 lb-ft of torque, while the four-barrel option made 266 horsepower and 301 lb-ft. Both shared the Cleveland’s overhead-valve, cast-iron architecture with five main bearings. Notably, the high-output 351HO had already been dropped from the lineup by 1973, leaving the 2-barrel 351 as the only engine still available with factory Ram Air induction.
