Many of the finest, highest-performance muscle cars of this era were ridden very hard, either road or track, and many acquired the scars of battle, misguided modifications, and even abandonment. 1971 brought lower compressions and low-lead gas, but all was not lost - the Buick Grand Sport 455 Stage One still pumped 345 horsepower from four-barrel carbs and dual exhaust, with functional hood scoops feeding the ram-air induction system. Heavy duty suspension and springs help keep everything rubber side down.

Stage One cars use custom cylinder heads and larger valves, an aggressive camshaft, and a Rochester Quadrajet four-barrel carburetor to maintain their category-leading performance. Many feel the 345 HP rating is a major understatement, and the documented performance of a 13.3 quarter mile and 105 mph top speed leads many testers to believe it could actually be more than 400 HP.

This fine muscle car has excellent Burnt Orange painted surfaces, excellent chrome and trim, and impeccable panel gaps throughout. It rides on the factory wheels with Goodyear Wingfoot radials. Inside, the interior is very nice and stock in appearance, with clean carpets and crystal-clear glass. The Gran Sport appearance details included a custom painted hood, accent striping, dual hood air scoops and special badging. Heavy-duty suspension, disc brakes, and a 3.42 rear end rounded out the package. With the massive 455 cubic-inch V-8 out front, there are few cars of the era that can come close to the speed and torque of a well-tuned example such as this. Poised for your next performance drive, or nearly any classic car event, this lovely GS Stage One combines the classic lines and rubber burning performance that every car guy admires.
