The Series 70 (models 70 and 75) was a full-size V8-powered series of cars produced by Cadillac from the 1930s through the 1980s. It replaced the 1935 355E as the company's mainstream car just as the much less expensive Series 60 was introduced. The Series 72 and 67 were similar to the Series 75 but the 72 and 67 were produced on a slightly shorter and longer wheelbase respectively.
It was time for another facelift in 1964 and really a minor one. New up front was a bi-angular grille that formed a V-shape along both its vertical and horizontal planes. The main horizontal grille bar was now carried around the body sides. Outer grille extension panels again housed the parking and cornering lamps. It was the 17th consecutive year for the Cadillac tailfins with a new fine-blade design carrying on the tradition. Equipment features were same as in 1963 for the most part. a completely automatic heating and air conditioning system controlled by a dial thermostat on the instrument panel, was introduced as an industry first. The engine was bumped to 429 cu in (7.0 L) OHV V8 for 1964. 340 hp (254 kW) was the result.
