RCC Motors is pleased to offer this powerful 1970 Buick GS 502. This was the most exciting year for Buick muscle cars. GM finally lifted the ban that intermediately sized cars cannot exceed 400ci’s. Therefore, Buick stuffed a brand new 455ci in its newly restyled GS models. The 455 spun a hotter cam with bigger valves and kept the functional hood scoops, sucking up plenty of cold air. The 455s were underrated at 350hp, but an astonishing 510 lb-ft of torque! A Stage 1 option was available with an even hotter cam, bigger valves, and a revised carburetor. Buick rated it at 360hp, but some experts believe that to be closer to 400hp. Somewhere along the way the original engine in this car was gone. It was replaced with a GM crate 502 HO big block producing 450 horsepower and 550 ft/lbs of torque. Some aftermarket front seats were fitted as was a B&M shifter. The car features power disc brakes, and power steering. It is extremely reliable and can be driven anywhere. It’s custom aluminum radiator keeps things cool. It has been a local Southern California car since at least 1975, and maybe from new. While no longer in show condition it represents a nice driver that’s ready for the road.
