1976 Ford Ranchero: In 1972, a radical change occurred in the Torino and Ranchero lines. The sleek, pointy look of the previous year's model was replaced with a larger, heavier design. Most prominent was a wide, gaping 'fishmouth' grille and a new body-on-frame design. There were still three models available; the now-standard 500, the new Squire with simulated woodgrain "paneling" along the flanks, and the sporty GT. Engine choices remained basically the same beginning with the 250 cubic-inch six-cylinder and a selection of V8s that ranged from the standard 302 to Cleveland and Windsor series 351s, plus the new-for-1972 400. The 385-series V8 (the 429 for 1972-73; the 460 for 1974-76) was still available. However, all suffered from lower compression ratios to better meet new emissions standards. The 351 cu in (5.8 L) Cleveland could still be obtained in tuned 4-V Cobra Jet form through 1974. A four-speed manual transmission was available on Cobra Jet-powered GT models.
The 1973 Ranchero saw a redesigned front end to meet new federal standards for front impact protection. Aside from slight cosmetic differences, the Ranchero would remain basically the same until the Torino's final year, 1976.
