checking compression Inline 6

Can you check the compression with the engine out of the truck?
Is it possible? How would you go about doing this?

Same as in the truck. Plugs out,throttle open or carb off if it's already off. Hook up battery to starter and either put a switch in or jump the solenoid. Use gauge as usual. Make sure engine is stable and nothing is going to get caught on ring gear etc
