1987 Chevrolet R30 Service and Repair Manual

Four engines serve them — a 4.8L inline-six of 292 cubic inches, gasoline V8s of 350 and 454, and the 6.2L diesel of 379 — all overhead-valve, none turbocharged. Custom Deluxe, Scottsdale and Silverado make up the trim range.

Known issues on the 1987 R30. What decides the condition of one of these trucks now is how it was worked and how it was maintained, and the manual speaks to both: engine specifications and overhaul procedures for the inline-six, the two gasoline V8s and the diesel, clutch, transmission and axle work, brake and steering service, and wiring diagrams that cover cab and chassis versions as well as finished pickups.
