The Chrysler 300K was introduced for the 1964 model year, and was the tenth variant of the 300 Letter Series. The 300K saw the reintroduction of the Convertible body style alongside the two door Hardtop. A 6.8L (413ci) 'Wedge' V8 engine was offered in standard or optional "cross-ram" configurations. The 300K saw its price reduced compared to its predecessors in order to increase sales, making the variant the best selling of all Letter Series cars. Only available for the 1964 model year,  the 300K was replaced by the Chrysler 300L.
