If you mean, is the position of the number one cylinder roughly at 3:00 O'clock as your facing the engine bay from the front of the truck, then that is approximately where it is at on my 235. But really, what I would do is crank the engine to where it is at top dead center (TDC) on cylinder one, (maybe back it off a few degrees), scribe the position of the number one plug wire on the outside of the distributor, remove the cap, and adjust the distributor so that the rotor lines up with that scribe mark. The result should be that the rotor provides power to the number one plug when the number one cylinder is at TDC (or a few degrees advanced). This should be close enough to get the engine running. From there, you can adjust the timing using a timing light. I believe this should work, but you might want ot wait to hear from others as I am a relative newbie and self taught when it comes to auto repair.
