The legendary J2X was a limited production racing/touring car. Even though only 83 were produced between 1951 and 1954, these were the most successful racers of the Allard collection. Although the Allard Motor Company never produced its own engines, it successfully integrated existing American V-8 power plants into its cars to threaten the dominance of racing circuits by larger producers. Factory Allard J2Xs were usually equipped with a Ford-Mercury flathead (or even exported without an engine), but it was the 331 cu. in. Cadillac and the Chrysler 331 Hemi Firepower that made its exploits legendary. At the rear, the J2X’s sported a deDion differential.
