1994 Chevrolet C3500HD Service and Repair Manual

This factory service and repair manual for the 1994 Chevrolet C3500HD documents three V8s: the turbocharged 6.5-liter diesel of 395 cubic inches, the 7.4-liter 454 and the 5.7-liter 350. The chassis itself is singular — a two-door conventional cab and chassis in Base trim, sold to be bodied for dump, flatbed, utility or wrecker duty. The specifications here are written for that bare truck, as it stood before whatever equipment ended up bolted behind the cab, which is the state a rebuild starts from.
