Vehicle features are based upon trim level, accessories and options may vary CHECK OUT THIS ONE FAMILY OWNED NORTH CAROLINA CAR. IT'S A RARE 1967 GS 400 For Buick, this meant the car had a similar top-speed and better acceleration than its primary competition. The other advantage was that the Buick could be equipped with GM's new Buick Super Turbine 400 automatic with three speeds forward and switch-pitch torque-converter (aka the Turbo-Hydramatic 400). The Chevelle 396 would not be so offered until 1967, and without the switch-pitch feature.
Of course, in this era, any small edge was of high importance in racing, whether impromptu street drags between lights, or sanctioned quarter-mile events at drag strips. And for muscle cars, racing meant one thing: straight line acceleration. As tested, the GS 400 would do 0–60 mph in 7.6 seconds. Unlike most other muscle cars of the day, the GS 400 came standard with decent brakes--Buick's famous finned alloy drum brakes, which resisted fading far better than anything this side of front disc brakes.
For 1967, there were two big improvements. Optional Delco-Moraine opposed-piston front power-assisted disc brakes improved braking potential even further, and the "nailhead" 401 was replaced by an entirely new, very modern big-block Buick V-8 of 400 cid. The new motor belted out 340 hp due to better breathing by means of larger valves, allowing for more power at a higher rpm, with peak at 5,000. Torque was still nearly as good as before, with 440 ft-lb. The new engine also went on a diet, weighing in a full 85 pounds less than the 401. This improved handling and steering. A new grille and trim changes made the rest of the package different from 1966.
