Timing. Find TDC of the firing stroke on #1. The rotor should be fairly close to a contact in the dist. This will be the wire going to #1 and rewire from there. I like to pull the valve cover and watch the valves to ensure your on the compression to fire stroke when bring the piston up then use something soft in the spark plug hole on the piston to find TDC.

The cap and rotor can be put on or in backwards. Make sure all the plug wires are on the cap correct. On the above answer, on the old cars, 1952 or older is was easy as they had cranks to turn over the motor very slow and you could put your finger in the spark plug hole to feel the piston reach tdc. Using the valve cover removal is now the best way to find it. I think the computer cars have a sensor on the cam to tell the computer where tdc is in relation to the firing of the plug wires.
