I just put my engine back together after new heads. I had taken the distributor out and put it back in, market it and everything. Went to start the car and it turns over but doesn't start. I have fuel, compression and air. I also have spark. However the timing must be completly off. So i was gonna do the thing where you pull the #1 spark plug and bring piston to TDC and then put the dizzy at #1. Problem is I don't know exaclty how to do this. When I put the dizzy in it only can go to one spot due to how the cam gear and dizzy gear are. Please help me with this.
