1970 Buick GS Stage 1 Convertible 455 CI Engine

3 hits ID #8106


The GS was reinvigorated by the increased displacement, with factory ratings climbing from 340 to 350 HP and from 440 to 510 lb-ft of torque. The optional Stage 1 performance package featured an extreme performance cam, large-valve heads and a unique Rochester 4-barrel carburetor. It is becoming increasingly difficult to find a genuine Stage 1 convertible. Only 232 were built, just 164 of which were produced with this example’s 400 Turbo Hydra-Matic transmission. Sold new at Joe Torres Buick in Rome, New York, it was the subject of a cosmetic restoration completed in 2007, at which time it was refinished in its original color combination of Fire Red with a Pearl White interior.
The engine was rebuilt using the original 455/360 HP Stage 1 high-flow heads, special Rochester 4-barrel carburetor and distributor, and the correct BB-code transmission and rear end are present. This 1970 Buick GS Stage 1 convertible is documented with Sloan Museum certification, including a full decoding from the original GM archives and the original dealer-financing agreement.
