1973-1987 Chevrolet C10 Squarebody Cotton T-Shirt

The 1973-1987 Chevrolet C10 redefined the American pickup by introducing wind-tunnel-tested aerodynamics and passenger-car ergonomics to a utility platform. This "Squarebody" generation set the template for the modern daily-driver truck, offering unprecedented ride comfort and cabin quietness.

Under the hood, the workhorse LS9 5.7-liter (350 cubic-inch) OHV V8 engine served as the line's backbone. Equipped with a four-barrel carburetor, this cast-iron small-block delivered 160 horsepower at 3,800 rpm and 260 lb-ft of torque at 2,400 rpm, prioritizing low-end pulling power over high-end speed.

Built on a carbon-steel ladder frame, the rear-wheel-drive C10 utilized an independent front suspension with coil springs and a live rear axle on leaf springs. Paired with a Turbo Hydra-Matic 350 three-speed automatic, this setup delivered car-like highway stability and a 1,500-pound payload capacity.

Chevrolet produced over six million units of this generation, which replaced the Action Line and was succeeded by the GMT400 platform. Today, they remain highly sought after by collectors for their ease of restoration, vast aftermarket support, and status as the peak of analog utility design.
