According to Jim Wangers' book "Glory Days", John Z. DeLorean coined the phrase when pitching the idea to Pontiac management in 1963.
I have no idea what stroker Dodge you're talking about, but if it isn't at least 450 CID, you're not encountering any modern-built Pontiacs... And the Buick? Much more myth than fact. I ran a couple of those Stage 1s in olden times. My 400 ram Air III would smoke 'em every time. Of course, we're talking real street racing, not magazine tests.
