I'm gonna assume you took the distributor out. First, determine which way the distributor turns. You may need to just stab it in anywhere and bump the engine with the starter to tell. Then, remove the distributor. Next, remove number one plug. Have someone bump the engine until you just begin to feel compression blow your finger out of the spark plug hole. Then find the timing mark on the balancer and bring it and line it up with zero on the timing tab. That's TDC. Now just pick a hole on the distributor and call it number one. It don't make a rat's *** which one it is. If there's a "1" marked on the cap, use it. Line the rotor up with that hole on the cap and stab the distributor in. Put number one plug wire in the hole the rotor's lined up with. The firing order is 1-2-4-3. Whichever way you determined the distributor was turning, just follow on around in that direction with 2, 4 and 3. Done. fire it off and time it with your light. Even if you didn't remove the distributor, you can still follow these deestruckshuns.
