When General Motors authorized engines up to 400 cid in its intermediate cars, Buick seized the chance to create its first muscle car, the 1965 Buick Skylark Gran Sport.
In actuality, the division's big-block V-8 displaced 401 cubic inches. Undeterred, Buick simply renamed it the "400." Teamed with a heavy-duty radiator and dual-exhausts, the 401 carried the same 325-bhp rating as in Buick's full-size models. ("Wildcat 445" on the air cleaner referred to the engine's torque rating.)
To Buick's credit, the operation was more than just an engine transplant. Any 1965 Buick Skylark Gran Sport -- hardtop, pillared coupe, or convertible -- got the convertible's beefed-up frame for better rigidity, plus specially valved shocks and heavy-duty springs. Buick added a thick anti-roll bar up front and enhanced the rear suspension with added links to fight axle windup and differential twist. Braking improved with enlarged front-wheel cylinders.
With the standard three-speed manual, the Gran Sport package added $253 to the cost of a regular Skylark. It jumped to $420 with the four-speed manual and to $457 with Buick's two-speed Super Turbine 300 automatic. The top available axle ratio was 3.73:1.
All 1965 Buick Skylark Gran Sports had to be ordered with bucket seats, a $72 "mandatory option." Positraction should have been mandatory, too. As with other high-powered intermediates, wheel spin off the line was a problem.
Nearly 70,000 1965 Buick Skylark Gran Sports were sold, and no one seemed to mind that it wasn't an all-out muscle car -- that would come soon enough.
