The 1965 Buick Skylark gran sport was manufactured by Buick Motors, a division of General Motors, to manufacture “to some extent” an American muscle car. Once referred to as a “gentleman’s muscle car” at its finest, Buick improved the A-body Skylark and called this selection the “Gran Sport” or also acknowledged as the “GS” in the years to follow.
The Gran sport was typically unlike the skylark as it had a heavier suspension and bigger front sway bar. The 1965 Buick skylark gs was called the GS 400 in 1967, and the Gran Sport became its model name that same year together with a new “400” engine reasonably unlike the legendary consistent but fading “nailhead” engine that was first launched in 1953.

1965 Buick Skylark Gran Sport
Buick sold more than 15,000 Skylarks with the Gran Sport selection that first year and almost the same number in its second, and no one appeared to care that it wasn’t completely a muscle car. Sales dropped a bit in the face of progressively high-performance and more trendy muscle cars from other companies when measured to those from the more heavy and pricey Buick.
1965 Buick Gran Sport engine
A 2-door coupe, the 1965 Buick gran sport engine spec was a big block V-8 essentially displaced 401 cubic inches. It created 325 hp at 4,400 RPM and 445-lb. ft. of torque at 2,800 RPM. Featuring a short 3.640-inch stroke and a hefty 4.1875-inch bore, it equaled 400.84 cu. in. This engine which ran on gasoline was actually 401 cu. In. (6,570 cc), but called a “400” in the Skylark Gran Sport by Buick to conform to GM’s 400-cubic inch maximum for transitional body cars. The camshaft has 295/295-degrees with a wait time of .431/.431-inch lift to trigger the 1.6:1 ratio shaft-installed rockers through pushrods. It had a Borg-Warner Super T-10 4-speed with a Hurst shifter mounted and a top speed of 179 km/h.
Ignition is supplied by a breaker-points dispenser. Braking was enhanced with bigger front-wheel cylinders and a broad anti-roll bar up front and improved the rear suspension with extra links to battle axle shut down and disparity twist. It had a rear-wheel drive standard manual three-speed gearbox with optional four-speed manual or Buick’s two-speed Super Turbine 300 automatic.
The 1965 Buick gran sport engine nicknamed the “nailhead”, has been a well-known force to reckon with regardless of where it is and that doesn’t even account for its status for stability.
