94 Silverado 3500 Dually Specs

by Rob Wagner

The 1994 Chevrolet C/K 3500 series dually pickup truck came in standard, extended cab and crew cab configurations. It featured twin-wheels in the rear, hence the moniker “dually.” The Silverado was a top trim model through 1998 in a line that included the Cheyenne and Scottsdale trims. For 2001, Chevrolet abandoned the C/K designation and named all its light-duty trucks Silverado. Its near identical sibling is the GMC Sierra.


The standard power plant in the 1994 Silverado 3500 dually was a 5.7-liter, 16-valve fuel-injected V-8. The engine had a 4-inch bore and 3.48-inch stroke. It developed 190 horsepower and 300 foot-pounds of torque. Buyers could choose from two optional engines. The 6.5-liter turbocharged diesel V-8 had a 4.06-inch bore and 3.82-inch stroke with a Borg-Warner GM-X series turbocharger. It developed 180 horsepower and 360 foot-pounds of torque, but there was a heavy-duty model of this engine that reached 190 horsepower and 390 foot-pounds of torque. The second option was Chevy’s 7.4-liter V-8 that displaced 454 cubic inches with a 4.25-inch bore and 4-inch stroke. It developed 230 horsepower and 385 foot-pounds of torque.
