The cast-iron Slant-6, nicknamed the "Leaning Tower of Power," earned a reputation as an engine that simply refused to die, with many units sailing past 200,000 miles without a major rebuild. It became the default workhorse for economy cars, police cruisers, mail trucks, and commercial fleets for decades. Surviving 1965 Belvederes with original Slant Sixes have become cult favorites for classic car enthusiasts. While some owners keep them bone-stock as time capsules, others lean into the motor's legendary toughness—building everything from budget daily drivers swapped with later-generation slant blocks to wild, turbocharged drift and drag projects.
