Dual quad = &quot;Super Duty&quot;. I think they built one SD Grand Prix in '63 (a white one) but it was a regular production option. (My Pete McCarthy book as at home so I cannot verify).

&quot;Six Pack&quot; = I believe the term you are looking for is &quot;Tri Power&quot; [img]<<GRAEMLIN_URL>>/wink.gif[/img]. That was the HO engine, which was a step down from the SD, but also readily available.
