1984 Chevy Half-Ton Specificationsby Christine Wheatley
Chevrolet, a well-known producer of domestic trucks, has been manufacturing versions of the half-ton truck since 1918. Considered a full-size light-duty pickup, the half-ton truck got its name because of the payload size it could haul. In 1984, Chevy's half-ton two-wheel-drive truck was labeled the C10, while the four-wheel-drive truck was called the K10. Chevy used this C/K designation on Chevy trucks until 1999, when it was replaced with the "Silverado" name. The 1984 C/K10 pickup was available as a four-door crew cab truck or a two-door regular cab truck, in short-bed or long-bed models.
The Chevy C/K10 had several engine options for 1984. A 250 cubic-inch in-line six engine was offered with 130 horsepower (hp) and 210 foot-pounds of torque. This engine had a bore of 3.875 inches and a stroke of 3.53 inches. Also available was a 305 cubic-inch V-8 engine with 160 hp, 235 foot-pounds of torque, a bore of 3.736 inches and a stroke of 3.48 inches. The company offered another 305 cubic-inch V-8 engine with 155 hp and 240 foot-pounds of torque. A 350 cubic-inch V-8 engine came with 175 hp, 275 foot-pounds of torque, a 4-inch bore and a 3.48-inch stroke. Beginning in 1983, a diesel engine became available on the truck: it was a V-8 engine displacing 379 cubic inches with 135 hp and 240 foot-pounds of torque.
Transmissions on the Chevy C/K10 truck included a three-speed TH400 automatic that had a 2.48-to-1 first gear ratio, a 1.48-to-1 second gear ratio and a 1-to-1 third gear ratio. Chevy also offered a three-speed 700R automatic; this was the first automatic overdrive transmission that GM produced. It had a first gear ratio of 3.06-to-1, a second gear ratio of 1.62-to-1 and a third gear ratio of 1-to-1. A four-speed SM465 was one of the manual transmission options; it had a 6.58-to-1 first gear ratio, a 3.58-to-1 second gear ratio, a 1.57-to-1 third gear ratio and a 1-to-1 fourth gear ratio. Also available was the M20 Muncie, a four-speed manual with a first gear ratio of 6.55-to-1, a second gear ratio of 3.58-to-1, a third gear ratio of 1.70-to-1 and a fourth gear ratio of 1-to-1.

On the long-bed model, the wheelbase was 131.5 inches while the length was 212 inches. The height was 65.8 inches on the C10 truck and 72 inches on the K10 truck.
