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 400 cid engine was replaced by the new 455 cid V8. The base model was rated at 350hp and 510 lb-ft 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 Quadrajet 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 rare and show quality vehicle is located at our Milwaukee showroom.
