The Gran Sport name has been used by Buick to denote several high-performance cars since 1965.

In 1970, the 400cid engine was replaced by the new 455cid V8. The base model was rated at 350hp and 510 ft-lb of torque. The optional STAGE1 version was rated at 360hp and 510 lb-ft of torque at 2800 rpm.
