This is what I call a KICKASS ride! The 1971 Buick GS!!!

According to the, the success of the 1964 Pontiac GTO encouraged Buick to produce a muscle car of their own. General Motors placed a corporate maximum of 400 cubic inches in their intermediates, but Buick just shoehorned their existing 401 cubic inch fullsize car engine into their Skylark to create the Buick Skylark Gran Sport.

Called the Wildcat 445 (due to its torque rating), this Buick engine dated back to the 1950s and was known as the “nail head engine” due to the size of its valves.
