DETROIT, Dec. 1 -- Dodge will start production of Dart models with a new, lightweight, 273-cubic-inch V-8 engine on December 9. This will mark the first time an eightcylinder power plant has been available for the popular Dart. “This engine was specifically designed for those customers who wish to combine the increased performance of a V-8 with the maneuverability of a compact car,” Dodge General Manager Byron J. Nichols explained. “To be known as the Charger 273, this engine will be the smallest and lightest V-8 built by Dodge but will offer a performance potential equal to that of the 318-cubic-inch engine now provided in standard-size Dodge V-8 models.” [Editor’s note: The 318 described here is NOT the same as the 318-cubic-inch engine later available in the Dodge Dart.] The horsepower rating -- 180 hp at 4,200 rpm -- means that the 273 will move the Dart from zero to 60 miles per hour in one-fifth less time than will the optional 225-cubicinch Slant Six engine, Dodge Chief Engineer George Gibson reported. The torque output of 260 lbs.-ft. at 1,600 rpm is the result of studied efforts by engineers to match the 273 to the Dart power train components. In effect, the lively performance qualities which have always been characteristic of the Dart can now be extended to an
even greater range.
I would "assume" Dec 9th was 1963 for production year 1964? Just a guess!:read2:
