1969 Plymouth Valiant: The Valiant was completely redesigned for 1967 model year and the station wagons and convertibles were dropped. The model range included 2- and 4-door sedans on a newly lengthened 108 in (2,700 mm) wheelbase. The design was straightforward and rectilinear. The body sides were mildly sculptured with a tapering lower feature line that widened toward the wheels. The new fenders had a vertical slab look. The grille was vertically split and subdivided horizontally. Vertical taillights were segmented and had a fanned-out look. Horsepower rating for the 170 cu in (2.8 L) Slant-6 engine was raised from 101 bhp (75 kW) to 115 bhp (86 kW) by installation of the slightly bigger camshaft introduced on the 225 in 1965, together with Carter BBS and Holley 1920 carburetors using the larger 1.6875 in (42.86 mm) throttle bore previously reserved for the 225, rather than the smaller 1.5625 in (39.69 mm) carburetors formerly used on the 170 engine.
For the 1968 model, the horizontal division bar was removed from the grille. A fine cross hatched insert was framed by a segmented chrome surround. Model nameplates were moved from the rear fender to the front fender. The 318 cu in (5.2 L), 230 bhp (170 kW) V8 was a Valiant option for the first time.
For 1969, a new one-piece, full-width grille, new taillights and trim were featured. Standard engines were unchanged, although refinements in the Chrysler Clean Air System (formerly Clean Air Package) produced better operating economy from the 6-cylinder engines. Improved brake adjusters, a more efficient power steering pump, and improvements to the optional Sure-Grip differential were also highlighted.
