The GSX may
have come late to the muscle car wars, but it certainly raised some eyebrows.
With the optional (most have it) 455ci Stage-1 V8, it posted some impressive
numbers: an underated 360hp and 510 ft-lb. of torque. Even though it was a
big, heavy, well-equipped car, it was one of the few that didn’t fear the
Hemi. Heck, let’s stir up the pot a bit: it’d run with the B-body Hemis all
day long up to 100mph. The GSX is the quiet, classy, understated beast
while the “Hemi Hype” grabs the headlines.
The GSX boasted comfortable buckets, a 4-spd manual w/Hurst shifter,
upgraded suspension with 15”x7” rallye wheels, power front discs, 3.42 posi
rear, and a distinctive appearance package with rear spoiler and a hood tach.
Your only two color choices were Saturn Yellow or the less popular Apollo
White. A/C and a TH400 automatic were available.
Sources vary, but somewhat less than 700 were produced for 1970, with about
400 equipped with the Stage-1 and less than 200 wearing Apollo white. After
1970, the package was available on any GS, including the GS350. Sales fell
to 124 in ‘71, and less than 50 in ‘72.
Parts are no problem and the mechanics are robust. Typical GM rear rear
window rust applies, so examine the edges and under and over the rear
package shelf. There are lots of made up cars -- be careful.
Predictions? If the current market holds, watch this one outperform the
market as a whole and begin to close on the category leaders.
