If you're looking for a rare and show-quality car, look no further
than this 1970 Buick GSX! The Gran Sport name has been used by
Buick to denote several high-performance cars since 1965. Since
Cadillac did not present an offering during the muscle car era, the
Buick models are considered the most well-appointed GM sports
models of the day. In 1970, the 400cid engine was replaced by the
new 455cid V8. The base model was rated at 350hp and 510 ft-lb of
torque. The optional Stage-1 version was rated at 360hp and 510
lb-ft of torque at 2800 rpm. The Stage-1 engine used cylinder heads
that were machined differently to accept larger valves and to
produce a tighter compression ratio. The option also included a
more aggressive camshaft, specially tuned Quadra jet carburetor,
more aggressive ignition timing, 5/8" oil pickup tube and a higher
numerical final drive. Also, in 1970, GM decided to step up yet
another notch with the GSX high performance package. The GSX was
Buicks' answer to the Pontiac GTO Judge and was introduced
relatively late in the 1970 model year. As a result, only 678 GSXs
were produced that year and only 400 with the Stage 1 engine
option. The impressive performance has become a legend unto its own
and is partly due to the light weight of the 455 (150 lbs less than
the 426 Hemi). The torque rating was also the highest output of any
American production performance car, a record held for 33 years
until finally surpassed by the V10 Viper in 2003. The 1970 Buick
GSX came in 2 colors, Saturn Yellow and Apollo White, a full black
interior, and has arguably the most extensive list of standard
high-performance features of any classic era muscle car. We are
thrilled to have this Yellow 1970 frame-off restored beauty in our
Milwaukee showroom. The numbers-matching Stage-1 455 has been
completely rebuilt and the owner states 1,100 miles since. The
transmission was replaced with a rebuilt period correct Muncie M22
4-speed manual with 3.64 limited slip differential. This is a
non-AC car and includes power steering and power brakes. Styling
features unique to the GSX include a distinctive full body length
black stripe crossing over the rear spoiler, hood mounted
tachometer and black front spoiler. Also standard are black bucket
seats, quick ratio steering, anti-sway bars front and rear and
quad-link suspension. This 1970 GSX is for sale in our Milwaukee
Showroom and can be seen at www.GatewayClassicCars.com; call (262)
