The ’65 Skylark Gran Sport came in two trim levels; the Special or the more uptown Special Deluxe. There were 15,800 of them produced this year with 11,351 two door hardtops and the balance two door coupes or convertibles. All units are equipped with the 401 CID V8 mounted with a Carter 4-barrel, which produces 325 bhp (242.35 kW) @4,400 rpm and develops 445 lb-ft (603.34 Nm) of torque @ 2,800 rpm. The Gran Sport can do 0-60 (97 km/h) in 7.8 seconds and the quarter mile in 16.6 seconds @ 86 mph (138.4 km/h). GM had a standing edict that none of its divisions would have a mid-sized car with an engine larger than 400 cubic inches, but Buick lists the 401 as a 400 to circumvent the ruling.
