You eventually recognize when the distributor is 180 out. A couple of loud bangs and a fireball out of the carb are tell-tale signs. When that happens, you lift the distributor up about an inch or two, flip the rotor around 180 and drop it back in. On GM engines, the oil pump shaft will not allow the distributor to drop in until it is ligned up. So it is a very simple procedure that takes all of 5 minutes to complete. Next crank it fires up and runs.
