The engine is the heart and soul of any car and the GSX is no exception. The Buick 455 held the crown for the most torque of any American mass-produced muscle car at the time 510-lb.ft and even though this engine had fewer horsepower than its other GM siblings, the Buick delivered amazing punch.
In 1970, 60 mph came in the GSX in just 5.8 seconds, not bad for a car weighing 3,874 pounds, wearing bias-ply rubber. The GSX could cover the quarter-mile in 13.38 seconds at 105.5 mph, according to a 1970 Motor Trend report.
There were 678 GSX cars built in 1970 and available in only Saturn Yellow and Apollo White. Of this number, 491 were yellow and 187 were white, according to the GSX Registry. Of the 678 cars, 199 had four-speed manual transmissions and 479 were optional automatics. And 278 had standard 455 engines, while the other 400 were Stage 1 powered. In 1970, the GSX package cost $1,195 and included much more than the special stripes. The Stage 1 engine was an extra $115. Also in the package were: A hood tach; stiffer shocks and suspension pieces; heavy-duty cooling; power front disc brakes; and G60x15 tires on Buick Rallye chrome-plated wheels. Other GSX specific standard equipment included: Power front disc brakes; 3.42:1 ratio positive-traction rear end 3.64.1 for manuals; special front stabilizer bar; heavy-duty front and rear shocks; and heavy-duty rear anti-roll bar.
