Posted two hours ago on BarnFinds dot com: Rare 455 V8 Project: 1970 Buick GS Stage 1 All General Motors divisions offered a mid-size muscle car in the 1960s and 1970s. That is except for Cadillac. At Buick, it was the Gran Sport (aka GS), based on the Skylark platform. Because the GS was a Buick, it was a more luxurious hot car than the Chevelle SS, Pontiac GTO, or Olds 4-4-2. The seller’s auto is a 1970 GS Stage 1 which came with a 455 cubic inch V8. Just 2,465 copies were produced in ’70, making for a rarer car than its GM contemporaries. Located in Columbus, Ohio, this Buick is a documented and numbers-matching project, available here on Facebook Marketplace for $22,000 The Skylark-based Gran Sport first appeared in 1965. Performance would continue to graduate until the 455 V8 debuted in 1970. The base version of the engine produced 350 hp. You picked up 10 additional horses when you opted for the Stage 1 package, though some industry insiders thought the output was closer to 420. When a ’70 GS 455 Stage 1 would go head-to-head with a 426 Hemi Mopar, we understand that the Buick would more than hold its own. Buick peddled just over 20,000 mid-size GS products in 1970, with a 350 V8 appearing in about half of them. If you drill down to a Stage 1 with the TH-400 automatic transmission, 1,785 copies would emerge (another 680 units had a manual transmission). The seller provides little to no background on this GS other than to say it’s a certified vehicle (by the Buick Gallery & Research Center). It comes with its build sheet and all the important equipment (motor, transmission, tachometer, etc.). We’re told that the mechanics of the vehicle have never been gone into at 55,000 miles. It appears to have been sitting for a long period given the amount of dirt and dust. The green paint may be original with the front clip wearing grey primer that was not recently applied. The black interior may be okay but we’re not sure as the driver’s bucket seat is covered with a sheet. If this car is everything that’s been advertised, what a great find and ride it might be – one day.
