As part of the consolidation of branding from the divisions to the GM brand, all the divisions morphed their motors during the mid-60s such that most of the divisions shared the same nomenclature (but for otherwise different motors. And they still screwed it up losing a law suit in the late 70's for putting a 350 Chevy into an Oldsmobile.) The Buick 430 begat their 455. The Olds 425 begat their 455. And the Pontiac 428 begat their 455. Chevy, being such a large part of GM I suppose, chose to be a tad different, and had a 454, begat from their 427. (Cadillac had a 472. Not sure how much it shared with others, but I think it shared some parts with the Olds motors.)
