    2x4 option


    Others have asked this question before, and I believe the answer is that there may have been a dealer installed 2x4. There are no 2x4 factory installed 401's in GS's.

    I am not absolutly positive, but I do believe it they did come 2x4. I was checking out some of my Uncle's old Buick stuff today and he has the window sticker from a '66 Wildcat GS. And one of the performance options which was on the car from the factory was the 425 Nailhead with the 2x4 setup. And I know for sure it was the original sticker.

    The dual quads were an option on the 'big' Buicks, like the Wildcat, Riv, etc.
    But dual quads were not a regular option on the Skylark GS. But if you had walked into a Buick dealer in '65 or '66, bought a GS, and told them to put a dual quad setup on it...the dealer would probably install them for you. Soooo....it wasn't a Buick option, but could be considered a 'dealer option'

    Johnny, is Don Coloumb your uncle? He's a good guy, I haven't seen him in years!...tell him Walt said 'Hi'....

    Don and Walt are right about the 2x4's. Only available from the factory on the 425, which with one exception, was only available in the big cars. Even the Interceptors came with 401's. It's funny that Pontiac screamed about the 401 breaking the GM 400" rule for intermediates, as Wangers himself admitted the '64 GTO that was used for the famous GTO vs. GTO magazine article was a full blown 421 ringer.
