You should be able to find the timing marks easily without a manual. Look on the pulley on the crank shaft (the big bottom pulley) and slowly rotate it around by bumping the starter.... OR by pushing down hard on the belt between the alternator and water pump pulleys (at the top) and then turning the fan to use the fan and belt to turn the crank shaft. (Yes, this works.) Pulling the spark plugs out helps to turn the engine by hand.
On the large bottom pulley, on the crankshaft, you will eventually spot a small notch on the back edge of that pulley (timing mark). You might have to clean that up to see it well. And there should be only one of these notches. Turn the crank pulley until the notch lines up with marks on a metal tab down on the lower driver's side of the front of the engine. Line the notch it up with the 0 mark on the tab.
Then, pull off the distributor cap and see if the rotor is pointed to the cap's tower for either the #1 or #6 spark plug wire. If not pointed to either, then pull the distributor and move the rotor and shaft until it points to one or the other (1 or 6). If it runs, then good. If not, then pull the distributor and turn it to the other plug (1 or 6). One of those 2 distributor positions should run fine.
And there is a way to tell if #1 or #6 is the right position but that requires looking at the valves with the valve cover off. If you want to do that, pull off the valve cover and watch the valves opening and closing as you move the timing mark on the pulley past the 0 mark on the cover. If the #1 intake is opening and the #1 exhaust is closing as the timing mark on the pulley passes the 0 mark on the tab, then #6 is ready to fire. And vice versa.....
