Your crankshaft or the front pulley on the engine will go around twice for every revolution of the rotor. So if your rotor is pointing at the number 6 cylinder now and you rotate the engine one revolution the rotor will then be pointing at the number one cylinder on the distributor cap.
The firing order is 1-5-3-6-2-4. You can see number 6 is halfway between the number 1.
Line up the timing mark on the crankshaft pulley with the 0 on the timing tab. Then check to see if the rotor is pointing to number 1 on the distributor cap. If not give the engine one revolution.
After you achieve that, take the key out so the engine doesn't turn over. Make some marks where the rotor is pointing on the distributor housing and also the distributor body in relation to what it sits on before you loosen the distributor hold down bolt.
You can use the bolt on the front of the crankshaft to line up the marks easier. I'm sure I said a lot of things you already knew I just wanted to explain things. Any more questions just ask.
