For Sale: 1978 GMC Pickup in Sherman, Texas

Squarebody sheetmetal, LS muscle, and a stance that means business. This 1978 GMC Pickup brings together tan and white paint, the High Sierra package, and a drivetrain upgrade that gives this classic hauler a fresh personality. GMC's squarebody generation arrived for 1973, and High Sierra occupied an upscale position in the trim lineup. These trucks enjoyed a long production run, so this pickup's appeal comes from its combination of equipment and modifications rather than a claim of low production rarity.

Under the hood, a swapped 6.0L LS V8 supplies the muscle, with stainless steel long tube headers adding to the hardware list. An aluminum radiator with dual electric fans handles cooling duties, while a 4L80E automatic overdrive transmission combines stout construction with a highway-friendly top gear. A B&M floor shifter puts gear selection within easy reach, and a 12-bolt rear end rounds out the drivetrain.

The chassis gets its share of attention with tubular control arms and a rear axle flip, giving the GMC a purposeful street-truck stance over 20-inch Racestar wheels. Power steering helps keep maneuvering manageable, while power brakes and front discs are welcome equipment for cruising. LED headlights bring updated lighting to the classic front end, and a spray-in bedliner adds a practical touch out back.

Inside, the black interior keeps things straightforward with a bench seat and no center console. Digital gauges update the driver's view, and an aftermarket sound system supplies the soundtrack. The tan and white exterior wears driver-quality paint, making this a compelling choice for someone who wants classic GMC character, modern V8 power, and a pickup built around enjoying the drive.
