what do you want to test, you want to hear it run? is the ignition hooked up? If so, all you have to do to make it run is put some gas in a soda bottle with an 1/8" hole in the lid and bottle feed it while its running through the throttle body with the air cleaner off. If the ignition is not hooked up, let me know. atleast check compression and make sure all 8 cylinders are within about 10% of each other.
