Starting in 1953 Buick offered an overhead valve pushrod engine known as the "Nailhead" for the unusual vertical position of its small-sized valves, which were compared to nails since their head diameter is smaller than other comparable displacement engines of the same era. The Nailhead V8 family used a camshaft with greater lift and duration to offset the smaller-sized valves and the restrictive intake and exhaust port diamaters. The small-diameter valves and intake runners allowed these engines to develop very high torque, with many engines exceeding one foot-pound per cubic inch, which was exceptional for the day.
