1973 Ford Mustang Fastback 351 V8 Custom Build, 4-Speed Manual, Ford 9-Inch Rear Why This Car Is Special The 1973 Ford Mustang holds a specific place in the pony car timeline that most people get wrong. Conventional wisdom says the Mustang hit its peak in 1969 or 1970, then slid into irrelevance before the Mustang II arrived in 1974. That narrative misses something important. The 1973 Ford Mustang was actually the last year of the original first-generation body style a body that Ford had been refining since 1971 with a wider, more muscular stance and a longer hood. After 1973, everything changed. The Mustang II that replaced it was smaller, lighter, and built on a Pinto platform. For collectors who want the last expression of the original Mustang shape, the 1973 model is the one to have. Ford produced just over 134,000 Mustangs for the 1973 model year, a significant drop from the highs of the late 1960s but still a respectable number for a car navigating the early emissions era. The fastback body officially called the SportsRoof is the most sought-after configuration of the 1973 model, combining the long roofline and near-flat rear glass that gave the car its aggressive silhouette. That roofline is part of why these cars photograph so well from nearly every angle. This particular 1973 Ford Mustang has been taken well beyond its factory specification. Rather than a numbers-matching preservation, what you have here is a purpose-built custom machine built around a 351 cubic inch V8 and a 4-speed manual transmission. The builder committed to a consistent black and red theme from the undercarriage all the way to the headliner nothing was overlooked. The result is a car that drives as deliberately as it looks. The VIN on this car decodes to confirm it is a 1973 model year Ford, assembled as a 2-door hardtop body style with a V8 engine designation. That foundation matches everything you see in the build.

Ford offered the 351 Cleveland and 351 Windsor in various states of tune throughout the early 1970s, and both were considered the performance backbone of the Mustang lineup during this period. The 351 Cleveland in particular had excellent cylinder head flow characteristics that made it a favorite for performance builds even by today's standards. What you are looking at under the hood of this car is a custom-built version of that engine, fitted with a performance carburetor, long-tube headers, and an MSD ignition system. MSD ignition is a well-established choice for street performance it delivers a stronger, more consistent spark than a standard points or stock electronic ignition, which translates to better throttle response and more complete combustion across the RPM range. The long-tube headers replace the factory exhaust manifolds and allow exhaust gases to exit the cylinders more
