1973 Chevy C10 Truck Specs

by Marlin Quintana

The C10 was the basic, two-wheel-drive version of Chevy's C-Series line of trucks. It was a half-ton truck available with either a 6.5-foot pickup box and 117.5-inch wheelbase or an 8-foot box and 131.5-inch wheelbase. With either wheelbase, customers could order the truck as a Step-Side, Fleetside or chassis and cab only. The 1973 model year brought a major restyling to the C-Series, featuring cleaner, squarer lines that would continue with minor changes through the 1987 model year.

Trim Levels and Standard Features

Four trim levels were available in 1973, beginning with the base Custom level, which had painted bumpers and hubcaps. Next up the chain of prestige was the Custom Deluxe, which featured vinyl upholstery, padded arm rests, chrome trim and a special Custom Deluxe emblem. The Cheyenne package added extra sound insulation, custom vinyl or nylon-and-vinyl upholstery, cargo lamp and custom interior trim. The Cheyenne Super, the top of the line, had everything the Cheyenne edition had plus upgraded interior trim and extra chrome body moldings.


The standard engine in the 1973 C10 was a 250-cubic-inch, inline six-cylinder engine that could produce 100 horsepower at 3,600 rpm and 175 pound-feet of torque at 2,200 rpm. A one-barrel carburetor was used with a compression ratio of 8.25:1. A 292-cubic-inch, inline six-cylinder engine with a compression ratio of 8:1 that produced 120 horsepower and 225 pound-feet of torque also was available. The third option was a 307-cubic-inch, V8 engine with a compression ratio of 8.5:1 and a two-barrel carburetor that produced 115 horsepower at 3,600 rpm and 205 pound-feet of torque at 2,000 rpm.
