Legacy Classic Trucks latest work gives one of GM's vintage pickups a modern drivetrain, while maintaining the original look.

Legacy Classic Trucks is best known for Dodge Power Wagon restomods. However, the company’s latest project switches brands by giving Chevrolet and GMC’s 1955-1959 3100 Napco 4x4 pickup a thorough upgrade.

Napco doesn’t refer to the model but rather a specific option for these pickups. Before 1960, GM didn’t offer its own four-wheel drive system. Instead, a kit from Northwestern Auto Parts Company was on the option list. Legacy Classic Trucks undertook the challenge to transform these classic work vehicles into something a little more useful for modern drivers. “This isn’t a restoration. Each Legacy Chevy Napco Conversion is completely rebuilt with all-new components,” company founder Winslow Bent said in the model’s announcement.

Legacy’s trucks start with original donor vehicles that retain as much of the factory body as possible. The firm builds each one to order, so customers can pick the specific look they prefer. For example, there are three front grilles available that correspond to different model years of the original Chevy and GMC pickups. Buyers can also get the standard Stepside bed like the one in these photos or the larger Fleetside as an option.

While the trucks look a lot like the originals, Legacy installs a new, fully-boxed frame, which is much stronger than the 60-year-old parts currently underneath the pickups. The firm also fits a revised suspension including remote-reservoir shocks and an adjustable sway bar, for improved handling.

Under the hood, these vintage-style pickups have ample power. The standard engine is a 350-horsepower (261 kilowatts) 5.3-liter V8, and the alternative is a 430-hp (320.7 kW) 6.2-liter V8. The rock-crawling grunt routes through either a four-speed automatic or five-speed manual gearbox, and both come with a low-range transfer case.

Legacy takes six months to build each one of these beauties. As the gallery below shows, the wait is definitely worthwhile. Click through the photos below to see the craftsmanship that goes into these amazing trucks.
