First you are going to need to take out the number one plug to find TDC (top dead center). To find TDC, you will need to either place a piece of electrical tape over the hole where the #1 plug was or have a helper place their finger over the hole. After that you will need to turn the engine over very gently or in quick bursts until the tape is blown off or your helper feels a quick burst of air from the whole. to wnsure you have TDC, try it a couple of times until you find the exact point where the piston is in its highest position. Once you have found TDC, you can replace the distributor. Make sure that when the distributor is going in you will need to offset the rotor button so it will line up with the #1 plug wire. You may have to try it a couple of times until you get it right. If the distributor does not go all the way down then the oil pump is not lining up. No worries, while the distributor is in and lined up slowly turn the crank until it drops nicely into its place. bolt it up and fire it up. you should be set at this point. Get a timing light and check just to make sure. You can tell if the timing is set right by the sound of the engine.
