Vehicle Description

Due to GM's restriction of 400 cubic inches for motors installed in their intermediate cars, Buick took its proven 401 cubic inch "Nail Head" engine, fitted it to the Skylark and created the Buick Skylark Gran Sport. There is no doubt the Buick was GM's division for Luxurious cars and they did not disappoint with the GS line as they added performance to the mix. The GS line carried the highest trim and options than any of its inter-divisional muscle car partners. After some years of success, 1970 saw the greatest Buick GS of all time. GM finally lifted its corporate ban of engines larger than 400 cubic inches in intermediate bodied cars. Buick responded by stuffing a brand new 455 cubic inch engine nto its restyled GS. The 455 boosted more displacement, bigger valves, and a hotter cam than the 400 and was also mated to a standard cold air induction through functional hood scoops. The 455 was conservatively rated at 360 horsepower, but even more impressive was the 510 pound feet of torque the car had to offer. To top it off, Buick also introduced the GSX appearance package with front and rear spoilers, contrasting stripes, meaty tires, hood tach and a heavy duty suspension. Many consider the GSX as the ultimate muscle car of its time.
