Buick GSX

“	If you are talking 1970 muscle, the Buick GSX deserves as much chatter as any of the other big-block V8-powered monsters of its era, and perhaps more. Once Buick talked itself into building a “mid-size” car with a motor larger than 400 CID, they didn’t cut any corners in making sure the GSX would hang tough with the best of the rest from GM. In fact, the only limitation they did place on the car was color choice, since you could only order a GSX in “Apollo White” or “Saturn Yellow.” Throughout the rest of the car you will find the best features from other GM branches, such as Pontiac’s hood-mounted tachometer. Conservatively rated at 360 hp, the 455 V8 had larger valves, a slicker cam, a Posi-traction rear end, and a revised Hurst transmission. Even the motor itself was designed lean and weighed 150 pounds less than that its brethren. Run the GSX through the traps and you will love the roar of its exhaust. If it’s too loud, or the torque is too much for you, maybe a rocking chair should be your next ride.	”
