1997 Chevrolet C3500 Service and Repair Manual
This factory service and repair manual for the 1997 Chevrolet C3500 has one unusual entry on its engine list and treats it accordingly: the 5.7-liter 350 is listed as running on compressed natural gas or gasoline, which brings a second fuel arrangement into the same overhead-valve V8. Beside it are the turbocharged 6.5-liter 395-cubic-inch diesel and the naturally aspirated 7.4-liter 454. Five bodies carry them, from the two-door standard cab pickup through the crew cab to the cab and chassis, in Base, Cheyenne or Silverado trim.
