Here is part of the ad: What you will love about this 4 door sedan is the super reliable in line slanted six cylinder engine called the Super Six. It is 225 cubic inch with factory electronic ignition from Rocket City Alabama. (Huntsville) This was the first year any engine in America stopped using points and this was made possible by the same company building the Apollo space craft that landed men on the moon around when Kennedy was shot! Its great on gas with its 2 barrel carb but runs fast anyway because it is from the muscle car era.
