Did we mention the massive amount of power this GS455 produces? History of the 1970 Buick GS455: The 1970 GS455 model is arguably the most popular year for Grand Sport enthusiasts being that it was the first year true big block performance offered by Buick. With that Buick offered some of their most aggressive body designs to better compete in the muscle car arena! This meant a potent 455ci V8 engine that featured a Stage I performance engine upgrade, along with the ever famous GSX appearance package. By doing so Buick proved that the GS455 wasnt your grandads luxury vehicle any longer, but rather a competitive muscle car that would produce more torque than anything else GM had to offer! The 1970 Buick GS455 was a dominating tire shredder that the public was waiting for! Description of this 1970 Buick GS455 For Sale: We are very proud to offer this 1970 Buick GS455 convertible that is finished in a gorgeous Ming Blue Metallic exterior over a gorgeous Pearl White upholstery. All of which is beautifully paired with its White convertible top. This particular example comes extremely well equipped with all favorable options, starting with a powerful, professionally built 455ci V8 that is mated to an M21 close-ratio 4-speed transmission that produces 525 horsepower and a massive amount of torque! Both the engine and transmission were fully rebuilt only 5000 miles ago. This included a fresh 10:1 compression 455ci crate block with T/A Performance Stage 2 oval port aluminum heads (2.13 intake/1.755 exhaust) that are fully ported, adjustable pushrods, aluminum roller rockers, high lift camshaft, Edelbrock Performer B4B aluminum intake, Holley Performance 750cfm double pumper with Quikcool heat shield, Ram-Air intake, MSD ignition system with Pro-billet distributor, ceramic coated long tube headers, fully welded 3"" stainless steel exhaust system with high flow performance mufflers and X-pipe. This is mated to the enhanced close-ratio Muncie M21 with Super Case by Auto Gear, built better internally to better handle serious torque. With this application comes a Hurst short-throw shifter, dual friction clutch, and heavy-duty throw-out bearing. The rebuilt Buick 10-bolt rear axle also houses a 3.23 Posi-Traction gear set. To enhance the road manners of this stellar Buick GS455 Convertible for sale, the chassis was fitted with a full Hotchkis TVS suspension system. Upfront, a huge 1 3/8"" sway bar was added along with 2"" lowering springs, adjustable steering arms, and AGR quick ratio steering box.
