350-Powered 1985 Chevrolet C10 Silverado Short-Bed Conversion

Description

The square-body C10 Silverado has earned its place as one of the most sought-after American pickup platforms of the past decade — clean proportions, a proven chassis, and just enough chrome and trim to telegraph its era without demanding a show-quality restoration to look right.

This '85 C10 Silverado has been modified under current ownership. The factory long-bed frame was shortened to short-bed configuration using the Holley/Brothers Trucks conversion kit, with the rear notched and fitted with a flip kit. The suspension has been dropped by approximately five inches in the front with drop springs and drop spindles, and seven inches in the rear. It wears a refinish in Marine Blue with custom red, white, and blue pinstriping, while replacement bed sides, tailgate, cab corners, and door lower corner panels were fitted ahead of the 2022 repaint. The interior has been trimmed in saddle brown with a custom center console, Retro Sound Bluetooth radio, aftermarket speakers, and a subwoofer.

Previously powered by a 305ci V8, the truck now features a 350ci V8 crate engine fitted under prior ownership, which sends power to the rear wheels through a Turbo 350C automatic transmission with a lockup torque converter. In 2023, the seller added Summit Racing cast iron cylinder heads, an Edelbrock Performer EPS intake manifold, an Edelbrock Performer 600 CFM carburetor, Flowtech headers, and an exhaust system with Dynomax Super Turbo mufflers. Various hoses, belts, ignition components, vacuum lines, and spark plugs are said to have been replaced at the same time, and the air conditioning system was also serviced.

This modified 1985 Chevrolet C10 Silverado is offered with an accident-free CARFAX Vehicle History Report and a clean Pennsylvania title in the seller's name.
