The Fastback coupe, also known as the SportsRoof, was one of three body styles offered for the 1971-1973 First Generation Ford Mustang Base Model. The Fastback, along with the Hardtop, were the two fixed-roof body styles offered, while the Convertible was the open top offering. The 1971-1973 Base Mustang fastback was available with a wide range of engines. The "L-code" 250 cubic inch (4.1L) inline six was the standard engine, while a range of optional V8s were offered. These V8 engines were available in various displacements and carburetor setups, and consisted of the "F-code" two-barrel 302 (4.9L), the "H-code" two-barrel 351 (5.8L), the "M-code" four-barrel 351 (5.8L), and the "Q-code" four-barrel 351 (5.8L). In addition to these small block V8 engines, in 1971, Ford offered two big block options: the 370hp "C-code" four-barrel 'Cobra Jet' 429 (7.0L), and the 375hp "J-code" four-barrel 'Super Cobra Jet' 429 (7.0L). For the 1972 model year, engine options were changed due to tightening emissions, seeing power outputs drop across the board. Big block V8s no longer offered, and the low compression "R-code" HO four-barrel 351 (5.8L) V8 was introduced. This low compression "R-code" HO 351 is not to be confused with the "R-code" 351 that was equipped in the 1971-exclusive Mustang Boss 351. The low compression "R-code" was only available in 1972, leaving the "Q-code" 351 as the top engine for 1973. Depending on the selected engine, 3 speed manual, 4 speed manual, or 3 speed automatic transmissions were available, all of which sent drive to the rear wheels. Production of the First Generation Ford Mustang ended in 1973 with the introduction of the Second Generation Ford Mustang for the 1974 model year.
