Buick-side 455 cu in torque-stroke, Nailhead family, Riviera personal-luxury — documented properly.
The 1970-only Stage 1 fitment on the Buick 455 cu in torque-stroke big-block closes the GM A-body Skylark muscle track on the Buick-side castings — distinct from the Chevrolet Chevelle SS 454 castings and the Pontiac LeMans GTO / Oldsmobile 4-4-2 GM marque-cross. The 1970-only GSX rallye-stripe body and trim package pairs Stage 1 with the GSX-specific grille and trunk trim; the Gran Sport 40th Anniversary Edition layers on the GS 455 base as a 1970-onward special-edition marketing package. The Buick-side 455 cylinder head / intake / balancer / camshaft and A-body Skylark cowl-tag discriminator anchor the marque.
