1991 Chevrolet K3500 Service and Repair Manual
This factory service and repair manual for the 1991 Chevrolet K3500 gives a technician one place to look for three engines' worth of numbers: the 454-cubic-inch 7.4L gasoline V8, the 379-cubic-inch 6.2L diesel V8 and the 350-cubic-inch 5.7L gasoline V8, all naturally aspirated and all overhead-valve. The trucks they went into are two-door — standard cab pickup, extended cab pickup or cab and chassis — in Cheyenne, Scottsdale and Silverado trim, and the body sections follow that same split.
