How do you get a 2.3 ford back in time after replacing the distributor and belt crankshaft and camshaft are lined up with there correct settings but there is something that is missing but cant find it?

If the camshaft and crankshaft are in proper time according to the marks you need to find the #1 cylinder and bring it close to top dead center (TDC). This can be done by removing the spark plugs and bumping the engine with the starter until cylinder number one pushes air out the spark plug hole. You can feel it with your finger (if you cover the hole with something it will blow it off).

Then rotate the distributor so you can insert it. The rotor should then be pointed to cylinder #1. This should be close enough to get it running so you can set the timing with a timing light. It is possible to be 180 degrees out of phase and have the motor run.
