    that's a Nailhead engine, 401ci although the advertising and paperwork is likely to make a lot of references to "400". this is because GM had a 400 cubic limit for mid-size cars.

    the dual quad intake and setup is very rare and quite valuable in it's own right.

    The 66 GS Skylark did not have a 2x4 option from the factory. The Q-jet was the factory carburetor option for the 66 GS Skylark. But, that does not mean the 2x4 was not added at the dealer.
