In mid-March 1971, a second design change for the GT-37 switched the striping to a reflective sword-style stripe sometimes referred to as the 1971 ½ GT-37. 1971 also afforded the customer the opportunity to choose any of Pontiac's optional V8s such as 350, 400, or 455 cubic inch models, including the 455 High Output (HO) engine.
The Tempest nameplate was phased out after the 1970 model year. For 1971, it was replaced by a new T-37 series that included each of the three bodystyles offered on the 1970 Tempest and T-37. After this year, the T-37 was dropped. In 1972 all Pontiac intermediates took the Le Mans nameplate except the GTO.
The 1971 Pontiac 455 HO was Pontiac's first engine to receive a special 800 cu ft/min (23 m 3 /min) Rochester Quadra-jet carburetor with specific jetting. The 1971 455 HO was rated at 335 hp (250 kW) at 4,800 rpm and 480 lb⋅ft (651 N⋅m) of torque at 3,200 rpm ( gross ).
Sometimes confused with the Buick designed and built 215 cu in (3.5 L) aluminum V8 that Pontiac had used in the two years prior, the "Pontiac 215" was an adaptation of Chevrolet's 194 cu.in. inline 6 currently produced and the new 230 cu in (3.8 L) overhead valve Turbo-Thrift straight-6.
Acadians were sold alongside the rest of the Pontiac lineup at Pontiac-Buick-GMC dealerships until 1971. When the mid-sized Chevrolet Chevelle was introduced in 1964 it was sold in Canada as the Acadian Beaumont ('Beaumont' was formerly the top-level trim of Chevy II-based Acadian), and in 1966 Beaumont became its own marque.
Pontiac removed the H.O. designation from the base engine, and simply decaled the now non-functioning shaker with "455". The "all hand-assembled" LS2 SD455 engine was rated at 290 at 4,000 rpm and 395 lb/ft at 3,600 rpm. All Pontiac engines included a new EGR system, which delayed the SD-455 program until late into the production year.

The Pontiac Grand Safari was Pontiac's top-of-the-line full-size station wagon offered from 1971 to 1978. The Grand Safari used the grille and interior trim of the Bonneville and Grand Ville passenger car series, and most (but not all) examples were trimmed with woodgrain paneling on the sides and tailgate.
