1970 Buick GSX 455 Stage 1

1970 Buick GSX 455 Stage 1 Additional Info:

There's no denying that 1970 was the pinnacle for the Muscle Car era. You had Chevrolet packing 450hp into their LS6 Chevelle Mopars were regularly shoving dual quad 426 hemis off the line with 425hp and Ford's BOSS 429 is the stuff of legends. However one manufacturer got lost in all the advertised Horsepower wars of the early 70's. The Buick GS line specifically their Stage 1s packed a 455ci V8 inside a GS and while they didn't have the advertised high horsepower numbers they had every other ...manufacturer beat by a mile in a less flashy statistic - Torque. The GS 455 Stage 1 left the factory underrated at 360hp but they created an enormous 510 ft. lbs. of torque from factory! That GS 455 Stage 1 factory engine's torque rating would stand as the most torque from factory by an American car manufacturer for over 33 years until it was surpassed in 2003 by a V-10 Viper. If that wasn't enough for you Buick offered one rare option above there GS - The GSX. Only problem was Buick was late to the Muscle Car party and by the time they unveiled the GSX Stage 1 in February of 1970 they had no way of advertising it as all the catalogs for the year had long been printed. So a mere 400 1970 Buick GS 455 Stage 1 GSXs were produced in 1970. Of those 118 had 4-speed manuals and 282 were equipped with the optional BB-coded TH400 automatic... This beautifully restored 1970 Buick GSX Stage 1 is one of those rare 282!
