AutoHunter Spotlight: 1973 GMC Sprint

January 6, 2026

Right now on AutoHunter, you can find this restored 1973 GMC Sprint, which is equipped with a 383ci stroker V8 built by S&J Engines and a 200-4R four-speed automatic transmission. Highlights include air conditioning, power steering, power front disc brakes, headers, and Positraction. Finished in Dark Red with a black vinyl top over a reupholstered black vinyl interior, this distinctive car/truck is now offered by the selling dealer in Oregon with a build sheet and clear title.

As part of the restoration process, the body was painted Dark Red, which looks great with the black vinyl top. Exterior features include chrome bumpers, body-color mirror caps, bright trim, a hydraulic bed cover, and a tray-style bed liner. Underneath, the Flowmaster exhaust system ends in a pair of outlets behind the rear tires.

This Sprint races people and cargo to their destinations on a set of 15-inch Rally-style wheels wrapped in 225/60 front and 245/60 rear BFGoodrich Radial T/A raised-white-letter tires.

The cabin received new black vinyl on the split-bench seat, which matches the black door panels and carpeting. Interior features include a Grant wood-rimmed wheel connected to power steering, power brakes, R-134a air conditioning, and Bluetooth-compatible Kenwood AM/FM/CD/USB/AUX stereo.

Instrumentation consists of a 120-mph speedometer, fuel gauge, warning lights, and readouts for the water temperature, oil pressure, and voltage. The odometer shows 18,579 miles; the title indicates this GMC is mileage-exempt.

Not only does this Sprint have a 383ci stroker V8 that was built by S&J Engines and bored .030 over, but the engine is also equipped with a variety of upgrades. That long list includes an Edelbrock 600cfm four-barrel carburetor, Edelbrock RPM Air-Gap intake manifold, Promaxx Performance Products aluminum racing heads, a Comp Cams street-grind roller cam, Scat Pro Series I-beam connecting rods, a Scat steel crankshaft, and Patriot ceramic-coated headers. According to the included build sheet, the engine generates 400 horsepower and 400-plus lbs-ft of torque. A 200-4R four-speed automatic transmits the 383’s power to an Auburn Gear Positraction rear end with 3.42:1 gearing.
