A 1956 Buick Special barn find doesn’t usually come with a $900,000 price tag, but this one earned it: twin turbos strapped to a 401 Nailhead V8 push output to roughly 800 horsepower, backed by Ride Tech suspension and a Corvette C6 independent rear end. The Nailhead’s origins as a quiet 236-horsepower luxury engine make the transformation even more remarkable. Here’s what makes this one of the more unexpected restomod builds in the muscle car world.
This 1956 Buick Special carries Buick’s famous Nailhead V8, a 322 cubic inch small-block nicknamed for its odd, undersized valves, paired with the smooth-shifting Dynaflow automatic. It was Buick’s value play for 1956, yet the engineering underneath punches well above its price class. Six decades later, the Nailhead is still a cult favorite among builders and collectors alike.
Ken Becker has owned this red-and-black 1956 Buick Special for twenty-five years, long enough that he describes it as a member of the family. The Special was the cheapest Buick you could buy, which makes it easy to overlook and wrong to dismiss. It carried a 322 nailhead V8, and its body style had helped introduce one of Detroit’s genuine styling breakthroughs. Read on for what the entry-level Buick got right.
Buick built the Special as its cheapest model for two decades, but the 322-cubic-inch V8 standard in 1956 still made it a genuine performer, not just an economy choice. The three chrome ventiports on each fender were Buicks own status code, telling buyers exactly where the Special sat below the four-port Super and Roadmaster. With 334,000 built across five body styles, it was anything but unpopular. It also represents one of the last years before the Special name disappeared entirely.
Buick built well over a hundred thousand Special sedans for 1953, and yet this ordinary four-door quietly marked the end of an engine era nobody at the time realized was closing. A brand-new V8 was already going into more than half of Buick’s output that year, just not into this car. Here is why Buick held its most affordable model back, and what else changed underneath in the same twelve months.
Buick”s entry-level 1957 Special hid something genuinely unusual under its hood: a 364 cubic-inch Nailhead V8 named for its oddly small, sideways-mounted valves. Detuned to 250 horsepower for the budget-minded buyer, it still became one of the most enduring engine designs of its era. Read on to find out why hot rodders still chase Nailhead blocks decades later.
