1987 Chevrolet V20 Service and Repair Manual
This factory service and repair manual for the 1987 Chevrolet V20 covers a four-door sport utility built in Base, LT and SS trim with three listed engines: a naturally aspirated 6.0L OHV V8 of 364 cubic inches, a naturally aspirated 4.2L DOHC inline-six of 256 cubic inches, and a naturally aspirated 5.3L OHV V8 of 325 cubic inches. That breadth is why the engine chapters run longest, since each displacement carries its own clearances, torque values and diagnostic data.
