The 1986 Chevrolet Suburan came with two engines. The 5.0L - V8 and the 5.7L - V8. Very hard to tell these engines apart. If you will look under the hood you will see a placard somewhere on the radiator mounting bracket or under the hood itself, with the engine size listed. Also listed there will be some other inforamtion like Spark Plug gap.
