In the case of Buick, the 1965 Gran Sport 400 was the intermediate Skylark. Although a V8 was already offered in the Skylark, the Gran Sport had the largest engine permitted by GM - a 401 in³ Buick V8. This engine produced 325 hp (242 kW) and 445 ft.lbf (603 Nm). Buick sold more than 15,000 Gran Sports that first year, and almost that many the next. Sales fell somewhat in the face of hot muscle car competition, and Buick introduced the Stage 1 option for 1969. This limited (less than 1,500 cars) version produced 340 hp (253 kW) and 440 ft.lbf (597 Nm).
A 340 in³ version, the Gran Sport 340, was added for 1967. It produced 260 hp (193 kW) and 365 ft.lbf (495 Nm), and less than 4,000 were sold. It was replaced the next year with the Gran Sport 350, and similar Gran Sport California, which used Chevrolet's 350 in³ small-block engine. Sales of the little-brother Gran Sport doubled, and were up to almost 10,000 for 1970. The Gran Sport 350 outlived its big brothers, lasting until Gran Sport production stopped in 1975Events January January 1 Watergate scandal: John N. Mitchell, H. Haldeman, John D.
